Great location, just stone throw from Hyde park, close to tube station and plenty of shops etc. yet on reltively quiet street. The room was OK, bit too small (there was no space between bed and window, which in 4th floor is not really a comfortable feeling), it was not the most maintained flat I've seen, but it was reasonable clean. The only realy issue was AC unit not working, which combined with late sun and generally hot summer made it for a difficult night. We asked to be moved to other room, and this wish was granted, the other room was much better (not a direct sun, window to the backyard and a little bit more of space made all the difference). Guys in the reception were nice and friendly, all together it was a nice experience.
