We stayed in Paolo's building (top floor flat) for 1 week and it was great. Paolo is a great host, super friendly, super helpful and always reply my messages quick, communication was excellent!!
The apartment itself was clean, will laid out and very central for London's attractions. There were 4 of us, Paolo gave us a folded bed in the living room and it was comfortable. Need not to say the double in the bedroom was very good and very quiet at nite.
Will come back for sure next time when I come London again.
