Nadia's place was as described. The location was good, easy access to metro. The neighbourhood is very interesting and multicultural, althougt we wouldn't suggest it for single female travellers (we were a couple so it was great for us). The apartment and room is quite small but it was ok for us as we spent most of the day in city. Bed was quite hard for our taste therefore we think 4 nights was bit too much to sleep on it, but of course it depends on the bed you are used to. Their friend Fabio who lives in the other room was great, he was very welcoming and positive. On the 2nd day we all (including Nadia, Waldir, Fabio and all their friends) went to a street party and had a great time. All together we had a wonderfull experience in paris!
