My son and I just returned from a trip to London and Paris. The Chesterfield Mayfair Hotel was our first stop. I had emailed the hotel just after I booked our trip to secure a room with 2 double beds, seeing that I am traveling with my son. No problem, received a prompt reply, it would be taken care of. It was, however, the room we were shown first was drab, depressing and smelled. The next room we took for one night because there weren't any others, was equally drab and depressing, but we both slept well.
The next day we were upgraded as promised, however they wanted to charge us $200 US for the upgrade. I told them if I was going to spend that I would check out and move to the Ritz Hotel. Didn't think the hotel was worth it at that price, an extra $200 per night. So, upon that they upgraded us to a suite for no extra charge. I was considering moving hotels...but the suite was lovely. The only problem was the noise of cars outside our window at night. It made sleeping with jet lag a little difficult.
It is a lovely hotel if your room is nice, the suites are nice, the other rooms need a face lift.
I found the concierge to be very nice and helpful. He recommended a restaurant nearby the hotel for a very delicious dinner, VERY EXPENSIVE, but I knew what I was getting myself into. Try The Greenhouse if money isn't an issue, wonderful meal, beautiful restaurant and walking distance from the hotel. A wonderful French chef.
The bar at the hotel was cozy, great piano entertainment, however I do agree with another reviewer that said help in the bar is indifferent. It is though they are really doing you a favor by serving you one of their very high priced drinks--loose the attitude and it is a great hideout.
Would I stay here again, perhaps, if I could be guaranteed a suite on the interior of the hotel.
Great free computer use in the lower level, that was a plus, as I had some work to do.

We spent a weekend in London at the Chesterfield Mayfair - and if I could, I'd hop onto the next plane and head right back!

Our stay at the Chesterfield was perfect in every way. First of all, the location couldn't be any better. It's easy to get around from Mayfair as the Green Park tube station can be reached within 3-4 minutes and the Oxford Street shopping area is not more than 10 minutes away.

Moreover, the staff is truly exceptional. Everybody, from the doorman to the concierge, is more than willing to help you in every possible way. After checking into our room we found out that our bed was too short for my husband. Although the hotel was almost fully booked, an extremely kind lady at the front desk took care of our problem and accommodated us in "The Study" junior suite (what a wonderfully decorated room!) at no extra charge. Thank you once again!

We had a traditional afternoon tea in the Conservatory twice - both times everything was incredibly tasty and we were offered more of all the things we enjoyed most. Again, the staff was perfect.

Also, we stayed in for breakfast on both mornings and the choice and the quality of the food items on the menu and on the buffet is exceptional.

I can recommend the Chesterfield Mayfair in every way. I'm sure even travellers used to very high standards will enjoy every single minute at this fabulous hotel!

Booked through londontown.com after reading TA reviews. Family of 4 (2 teens, 2 adult - 1 in wheelchair) stayed 8 nights in 2 rooms. Yes, it was beyond nuts, I admit it right up front. but we wanted to be taken care of by a 5-star hotel. We really weren't taken care of as expected (see below), but it was a nice enough place to make our stay an enjoyable experience. As a disabled guest in London for the first time, I was glad that the hotel, as expected, is centrally located within a short walk of good breakfast & lunch places (Cafe Necco is excellent), the Ritz (Evan Evans tour bus pick-up location), Buckingham Palace, and London's extensive bus lines. The hotel doormen had to drag a portable lift to the doorway every time I entered and left the hotel. They eventually got used to the routine & were nice about it, but I still felt conspicuous. Lobby interior is inviting just like the pics, very British-clubby and elegant. Bar and restaurant are as nice as pics as well, but staff is a bit indifferent in the bar. Bathrooms are in the lower lobby and are not accessible at all. The hotel provided me with a lovely and quiet accessible room dominated by the king-sized bed, which had a very hard uncomfortable mattress and several too-soft pillows that made sleeping difficult. AC was loud but tolerable. Accessible bathroom had insufficient grab bars, and a sloped entrance ramp that made wheelchair access impossible without help, and the rickety tub chair was truly treacherous. Still I was very glad to have this room once I woorked out a system for myself - I used a manual wheelchair in the room, and switched to a rented electric one for outside use that I stored in the library at night. Hotel elevator (lift) was very small - I had to move the footrests back on the manual chair to fit inside, and it was a very tight fit for the electric one . Doormen assisted in retrieving & storing the ramp and wheelchairs but I had to get huffy with the night staff before they became more helpful. After they knew I needed them to be more pro-active in setting up the ramp, getting the wheelchair, etc., everything went much more smoothly. Still, I feel that for a 5-star, hotel, I shouldn't have needed to be assertive to get help (just with the night staff; daytime staff was usually fine). [Note: I found the London bus system to be very convenient to the hotel, and the busses were eminently accessible with excellent lifts.] Staff was not very helpful at all re: sightseeing and transportation tips and assistance, again, surprising for a 5-star hotel. I'm glad I'm self-sufficient and that I'd done all my own very extensive research in advance. Still an elegant small hotel in a very nice, safe neighborhood that makes a visitor feel very good. Prices are so ridiculously high (even though I'd been duly warned, the money drain was much worse when actually experienced) that your money gushes out of your hands like flood water - after 8 days in London I felt almost like it just didn't matter anymore, because I was so broke-what difference is another $40 breakfast of 4 bottles of juice, a small fruit container, and 2 muffins, anyway, after a week of crazy prices? Enough to make anyone punchy...!

We had a wonderful stay at this hotel. The staff are really friendly and the manager provided complementary breakfast after some confusion on the booking, and then a free room upgrade as it was our 50th wedding anniversary. What more can you ask for.

The hotel is well situated in the heart of London and the breakfast and evening meal were excellent. The room and bathroom were spacious and quiet.

We would gladly come here again in the future.
