This was my first experience with booking via airbnb. And I have to say it's a great alternative to a hotel. I went to London just for a few days, to see my favourite bands in Hyde Park, and I needed a place not very far from it (or accessible enough) for reasonable price. Julia's place is close to underground station - wasn't too hard to get there from Heathrow. Also, it took me about 20 min to get to the centre of the city (Marble Arch).
Julia is a wonderful host, very helpful and kind. Was there for me whenever I needed some advice or just wanted to chat a bit.
The room was just like in the picture - big and light, the bed was really comfortable.
I'm glad my first experience turned out good, I'll definitely use airbnb service again. And I wouldn't hesitate to stay at Julia's during my next visits to London
