I stayed 3 weeks at Denis's place, and I felt just like home. The room is bright and clean, everything was ready for me. also the location is quite convenient for traveler since you can get to old street station, shoreditch or dalston on foot. Unfortunately I couldn't spend much time with denis but he was very welcoming, friendly. If I happen to have any chance to stay in london again I'd definitely stay at this place. Highly recommended!!
