The room in this flat is exactly what one needs: ensuite facilities, quiet and in a central place from where one can reach quickly most of Central London (buses taking you into Waterloo, Westminster and other popular areas stop just a few metres from the building's entrance, Vauxhall and Kennington stations are walking distance and one reaches quickly Waterloo by bus as well), a rack of London bicycles is also a couple of minutes away.
There are plenty of restaurants close by, my favourite was Taro, serving Japanese food, but there's a Pizza Express, pubs and several takeaways, there's a Tesco express just downstairs, and I was able to receive packages in the petrol station also downstairs.
This place is an excellent alternative in the real original spirit of Airbnb since the flat is the home of the owner, whom is very friendly and welcoming.
