Staying at Andrey and Larissa's place was a great opportunity to rest in a very good location. It's really close to London downtown, the underground, many shops are available as well. The communication and attention from both of them was really nice, they even let us check in earlier and Larissa was a very polite and kind host. The sofa/bed is actually very comfortable.
We'd definitely recommend to stay here. Thanks Larissa and Andrey! :)
