First it was a bit hard to reach Alessandro, but after we did he was very nice and helpful. He is a nice, open person, who is willing to help in anything (suggestions where to eat in the neighborhood, what show to see etc).
The house is freshly renovated in a nice quiet street, yet close to the tube (and good bus lines) and not far from the city.
The apartment is also freshly furbished, you can feel like home. The bathroom is perfect (even if tiny).
Everything was clean and well kept.
Alessandro waited us with a bottle of wine and candles, nice. :)
This is a very nice place to stay in London, we definitely will go back.
