Had a lovely stay at Xavier's home. The room is generously sized and comfortable and the location can't be beat - I had an easy time jumping on a bus or several metro lines or just walking to my destination. Area is safe and fun to explore - lots of shops and restaurants. Xavier is a great host - we only overlapped a bit since I was out a lot trying to see as much of the city I could, but he was friendly and very communicative whenever I had a question. Would definitely recommend.
