Lina is a very friendly host who we did not meet in person but who always replied asap to our messages and was happy to help e.g. with letting us store our luggage before check-in on the morning of our arrival.
The house is located in a good area when in comes to transport links and supermarkets and Battersea park around the corner is a nice bonus.
Accommodation itself is fine, the shared bath and kitchen bring waiting periods at times but the other guests were friendly and we felt ok about it - a bit like a flat share or youth hostel. Spacewise the rooms are a good value for their money given the easy access to central London.
