We had a nice big room, with kitchen facilities and a seating area. Biggest room we've had in London and handy having a fridge for food and drink. Public areas are very nice and there is an outside area, which will be good when the weather is warmer.
Hotel is a couple of minutes walk from Gloucester Road tube station and there was a Tesco, Boots and Waitrose at the station so handy for stocking up on milk, coffee, wine etc for the room. Being on the Picadilly, Circle and District tube lines, we were anywhere in central London within 10 minutes, and around 40 mins to Heathrow, which was partly why we booked here.
Location wise, i would have preferred to be more centrally based and within walking distance of Covent Garden, Leicester Square etc, as opposed to having to get the tube everywhere. There did seem to be some restaurants in Kensington but we preferred going out in the centre.
Brilliant hotel/suites though and really enjoyed our stay and the room.
