This is a quite good upscale small hotel which is nicely located. Though this is a part of Hilton chain, don’t expect the normal HHonors Silver/Gold/Diamond perks (such as free breakfast or room upgrade) here. Review is based on a three night stay in June’09 (background of spending 80+ nights per year in different hotels around the globe)

Location:
Very good location almost next to the Gloucester Road tube station with a number of pubs, restaurants and shops in the neighborhood. Still in rather quiet residential street, i.e. not immediately next to any bar etc. Walking distance to Natural History Museum, Science Museum and V&A. Harrods not too far away either.

Room:
Had a deluxe room in the third floor which was large, especially by London standards. Certainly more than enough for me as a single traveler. Room had all the normal equipment e.g. mini bar and safe.

Décor can be summarized as quite extravagant with lots of gold. Style is quite “Arabic”, especially in the bathroom. Not exactly my style, but still not too tacky as such. Bathtub included a whirlpool mechanism

Room was facing inner garden, no noise whatsoever. It was very clean and well kept

Service:
Nothing to complain about, quite fast and effective service whenever needed. Though I’m low maintenance visitor, i.e. didn’t test the knowledge level of concierge or anything like that

Etc:
As HHonors Diamond member I’m used to receiving complimentary breakfast / room upgrade / water or wine in room, which obviously is a part of why I use Hilton hotels a lot. However, here I got absolutely nothing despite Waldorf-Astoria also being a part of Hilton chain. It seems that they have their own policy, unfortunately, as the same happened to my colleague who is also HHonors Diamond. So just be aware of this.

There’s no Executive Lounge in this hotel.

Would I return there?
I might, depending on the price (now that I’m aware of those peculiarities related to HHonors<=>Waldorf relationship so that would not a disappointment anymore)

I loved stayed at the Bentley so much, it would have to be one of my top hotels! We actually found the Bently via wotif.com after moving out of a terrible hotel our travel agent had booked for us. The location of the Bentley was perfect, only a couple of mintues to the tube station (sorry I don't remember the station name). We walked from the station to the hotel late one night and felt safe - its a very nice neighbourhood. There is also a few good places to eat close by. Our suite was exquisite! The suites feel a million dollars! The size of the room was impressive...very spacious. The marble bathroom was also very large and lovely. The staff we encounted were very professional and made our stay very welcome. We very much enjoyed the Bentley.

A beautiful building does not make a hotel special - it's the service and this hotel does not deserve the distinction of Hilton's upper echelon chain, Waldorf-Astoria. From an understaffed front desk to a inept concierge, service is obviously not a priority here.

Having requested a rental car by email prior to arrival, we were told it would not be a problem to arrange upon arrival for pick up at the hotel. Upon arrival, it seemed to be a first time request and the concierge had difficulty with the request. Since our room "was not ready" at 12:30pm, we went out and the concierge said they'd work on the rental. When we returned, we were told that London rental companies place a 1000 pound hold on the credit card for rentals of premium cars. We had not been told any of this when we first made the inquiry and felt the way everyting was handled was poor. When I stated that it seemed like this was a new request for him, he stated that most guests have cars with private drivers! Insult? I think so.

The room was acceptable and well appointed. The location is ideal. But the service just turned us off and we canceled three additional nights to relocate to another luxury hotel where we enjoyed our stay immensely in a more spacious and comfortable room.

This hotel is very convenient if you use Underground service by Picadilly line from any of the terminals in Heathrow provided you are not carrying too much luggage. You alight at Glocester Road and the hotel is less than 150.M away. It is in a quiet street by Harrington-Garden, quite a bit of Cafe's like Paul's and the Michelin rated Indian-Restaurent Bombay-Brasserie is very close. The hotel too is compact and nice with a posh lobby and importantly I took a standard single room, but got upgraded to a deluxe room, which was very well designed. The bathrooms are in immaculate shape and the hotel staff were obliging and friendly. I got my room between wednesday and saturday for an average price of 170.GBP all incl, which I thought was phenominally good value for what you get. I did not use the spa or the restaurent except for desserts, which were delicious.
