Great place and probably the cheapest you can find that is still close to Central London.
Tube is 1min away from the flat.
Room is perfectly fine for two people. Bathroom might be shared with others, depending whether there are other guests or not.
Kitchen is not included in the AirBnB (not needed if you are only for a short stay in London anyway).
Me and my GF spend three nights in London on the weekend and could always go anywhere from the tube station near the AirBnB and also come back at any time.
Natalia is really friendly and always for any questions/problems. Communication was smoothly before and throughout our journey.
