I stayed at Natalia's place for two full weeks while I was in London for research. The house itself is modern, well equipped, and very conveniently located - literally right next to Latimer Road tube station, and about 15 minutes walk from Portobello Road. I didn't get to meet Natalia as she was away during that time, but she was always very communicative, and the room included a few thoughtful touches like chocolates and herbal tea. I had a great stay, and value for money in this part of London.
