The location of this flat is priceless, we didn't take the underground once because most things are within walking distance. There are many pubs, cafes and restaurants all around and london eye and buckingham palace are easily reached within 30 mins (walking distance).
My friend and I got separate rooms in this house, and for one person with a small suitcase (cabin baggage), the space was more than enough. This room is the biggest in the house and comes with a little kitchen. Everything was very modern and clean, and in case you forget to bring a UK converter, you can even plug your phone in directly with a usb cord - very convenient! The adjacent bathroom was also very modern and the shower was perfect.
I was not bothered by the noise at night, although the pubs are busy until very late.
Communication was very quick and the hosts were extremely friendly and were always available. I'd absolutely recommend this place to solo travellers or young couples who don't need a big hotel room and are interested to enjoy a good night out in the middle of London.
