Christian was a wonderful host, like having a friend in Psris but he was not intrusive. He even invited my husband and me for drinks with his wife Ghislaine one evening. His English is fine for basic communication and a booklet in the apartment is written in several languages so even instructions for the washing machine were clear. (There is a clean laundromat down the street for the dryer.)
The apartment is immaculate. The bed is comfortable, the kitchen adequate for simple meals and the bathroom is updated and roomy enough for comfort. Huge Windows open onto a lively Paris neighborhood with the requisite cafe on the corner. Once the windows are closed, the apartment is quiet.
The best thing about the apartment is location, location, location. The Metro is across the street and from there you can get to almost anywhere in Paris in about 30 minutes. The Metro is a breeze to use. You can walk to Notre Dame in about 20 minutes and to the Pompidou Center in about 15. There are great bakeries (our favorite Ernest and Vallentin has natural breads with incredible flavor), restaurants of all kinds, a large Carrefour grocery store and a pharmacy with staff that can speak English all within minutes of the front door. The fun Marchè des Enfants Rouge is 10 minutes away with its well priced international restaurants. The Chinese neighborhood with its grocery stores and restaurants is around the corner.
We would definitely stay here again and we were here for 12 nights!
