My husband and I stayed for 2 weeks in December. Great hosts and great apartment. We landed at CDG, took the train to the Saint Paul metro station where Vu met us and we walked the short distance to the apartment. The neighborhood is wonderful - many interesting restaurants, cafes, shopping. The streets are narrow and interesting. Lively during the day, quiet at night. Vu gave us lots of suggestions of things to do in and around Paris. The apartment was well furnished with everything we needed.
The apartment has 2 sleeping areas - a loft and a pull-out sofa. The loft area is quite small and close to the ceiling (you can hear people walking/talking upstairs). We recommend sleeping on the pull-out sofa, we also moved the mattress from the loft to the pull out sofa.
Highly recommended apartment and host!
