Very nice room on the 4th floor. Comfortable bed, large bathroom, sizable TV. Fairly well shielded from outside noise, however sounds carried quite badly through the walls and you could pretty much listen in on any of the neighbours' conversations.
Decor was lovely, especially the ceiling light. There was a partially frosted window between the room and the shower, which is interesting but I wouldn't recommend it if sharing a room with family or less-than-very-close friends.
The room got quite humid with the AC off (this was in December) but was alright with it on, although the temperature setting went straight from 'quite chilly' to 'rather toasty'.
Staff was very good and provided excellent service throughout my stay, which included bringing takeaway up to my room every night as I was in quarantine at the time.
Location is very central and fairly easily accessible by taxi coming from Heathrow. There were quite a few ambulances passing through the area but it was otherwise not unreasonably noisy, especially considering its central location.
Overall, I felt that I got my money's worth. I'd recommend it to others with the caveat that it's not for someone who's easily bothered by people in the other rooms.
