We stayed here in Jan 2012 for three nights - myself, husband and two daughters.
Our room was clean and spacious enough for the four of us as we were only really using it to sleep in. We didn't eat in the hotel, but did have a few drinks in the bar one evening with some friends. The staff were helpful and friendly - booked a taxi for us etc.
Camden itself is a lovely area, it was a bit cold for doing lots of walking about but I imagine in the summer getting a boat down the river would be lovely. The Tube station is a few minutes walk, there are also plenty buses that take you into the centre of London which pass by the Tube station. There are a few supermarkety type shops nearby that we got snacks from.
We really enjoyed our stay and were lucky enough to get a brilliant deal through 'top secret' hotels (we didn't know the hotel until we booked it) - definitely a bargain and I'll be looking to stay here again if at all possible :)More
