Cristina was a great host. She was in the apartment when we arrived and showed us the apartment. She then showed us a few important places in the neighborhood such as the grocery store. Christina's place in a great residential location, no souvenir shops anywhere, but the Metro was near by and in three stops we were at the d'Orsey museum. There was a pedestrian street about two blocks away with just about anything you need, such as restaurants, pharmacies, ice cream, and cheese shops.
One thing that may be important to some travelers is that the bedroom is on the second floor with a circular staircase leading up to it.
