Jennifer was very service-minded. She answered questions within the hour, and was very sweet and polite when we arrived at the appartment. The appartment was as described, very charming and cosy, and a nice bottle of wine was waiting for us upon arrival - along with a variety of cookies, crackers etc. The appartment was a bit cold during the night (we were there in late September), but we didn't use the heater, so I am sure that that would have helped. The bed was very nice, but the sofabed was a little short - so the shortest person should sleep on that one :)
The area is the best in Paris - no doubt (I used to live in Paris for a few years, so I know a lot of the other areas). It is close to almost everything, and we walked everywhere. A lot of nice shops, streets, cafés and restaurants in the area - especially Aux Charpentiers on 10, Rue Mabillon was amazing (try the beef tartar).
We would definately stay here again next time!
