We had a wonderful time at Sonia's apartment. The apartment is in a great location opposite the university and close to the underground. It is also a short distance to great night life. Living in an actual parisien apartment helps you to experience paris like locals (to some extent). The apartment was lovely. The only downside was that the second bathroom is a bit tired, and the toilet has limited ventilation and is next to the kitchen-- and there is no hand washing basin near the toilet unless you use the kitchen. We also couldn't find a washing machine...perhaps there was a communal one. Other than that it was super great. Sonia was a very good communicator.
