My friends and me were totally satisfied! The house is big enough, it is very modern and well-furnished. It is in a quiet district, although there is the police station nearby and you often hear sirens ringing. The apartment is very close to Caledonian underground station (less then one minute on foot!) where there is the Piccadilly line, very useful to reach the centre: the following station in that direction is already in zone one of London!
Alfredo, the owner, is very careful about his house in order to give a good service and he's very helpful.
Nothing else to say but..perfect accomodation!
