I definitely recommend Valentina's place. The place is very comfortable, the room (and indeed the whole apartment) is nicely furnished, and it is super convenient for the NW lines. Valentina and her sister Maria were excellent hosts; Maria was very communicative and pleasant to talk to. The only negative I can think of (which didn't bother me at all, but might be difficult for some people) is that it's a 5th floor walk up.
