great place :)
perks: the best neighbourhood to stay when visiting London. lots of areas around to work on the computer, eat, drink, dance (and even on the weekends the room was quiet and we could sleep even though there was a club across the street)
the place is easy to find, easy to get to, very nice and responsive host, a lot of amenities (washing machine!)
minus's: everything was quite small, the shower didn't have the hottest water and had moments of cold water out of the blue (though I must say that any time of the day there was hot water - which was great)
and for people with back issues the mattress might be a little soft.
