I had a lovely stay at Roberto and Vanessa's house. They are extremely friendly and polite and they made always sure that everything was alright. I really felt like at home and I am sure I'll try to go back whenever I'll need a place to stay in London. The room is large, and bright. The house is clean and never noisy. As for the location, the Piccadilly line is at walking distance, which makes it very convenient to reach the centre of London (in less than 30 minutes). Great Airbnb experience!
