We had a lovely time at Natacha's lovely apartment. Very spacious, welcoming, really comfortable, and overall enjoyable. Natacha was very helpful and responsive -- really a pleasure to deal with. Don't expect the most romantic/clean neighborhood but it's not like you won't feel safe or anything; in fact, it's very conveniently located, being very close to a lot of shops and two metro lines (2 and 11), and anyway not too far from all the sights. Very much recommended.
