I stayed some months at Monika's place and basically everything was fine. The appartment and the room are not that big, but this is expectable in the center of London. The location is very nice, close to the vivid quarter of Angel, where one finds a lot of pubs, restaurants, and shops, and close to King's Cross (10-15min walking along the very comfortable Regent's Canal). Monika was friendly and helpful during my stay and I found everything I needed in the appartment. So I would recommend it.
