We stayed here for three nights in November (10-13th). We took the Heathrow Express and took a nice walk from Paddington station, just about 10 minutes. We were able to check in right away and got a room on the 3rd floor with a view to Queens Gardens.
Our room was very clean and we could open the window all the way. All the facilities at the hotel were very nice, loved the hard wood floors! Breakfast is a bit expensive, but you can walk about 5 minutes and find many shops like Tesco Express and Sainsbury's for much less.
Hyde park is just 2 minutes away and we even took a nice walk to and from Oxford street. The neighborhood is very quiet as well.
The staff was also very helpful and assisted us with reservations at a restaurant during our stay.
The only down side is the same as with many hotels in London,The room was on the smaller side which is not too bad if you do not have large suitcases, the bathroom was however tiny and not very easy to close the door without some extra effort. My spouse said the room could have been more soundproof if they would close the gap between the door and floor facing the hall.
Overall I would recommend this hotel to anyone who wants a nice stay in London and not to far from the center.
