I can`t add anything fundamentally new to the previous reviews.
Housing.
The journey here from Charles de Gaulle airport takes about an hour and a half (RER + metro) no more. Metro stations are within walking distance: La Fourch and Guy Môquet. To each of them — 5-7 minutes. Near are Montmartre and the Champs Elysees, Pigalle square. It`s very convenient location for walking. Within a radius of 100 — 200 meters there are cafes, restaurants, pubs. Prices are inexpensive in comparison with the city center. On the street Clichy are grocery shopping. The closest is situated on the intersection Jackmon-Clichy. Carrefour network. A little further, in the direction of Place Clichy there are Franprix and others.
The apartment is comfortable. It is located in a quiet, peaceful neighborhood. The windows overlook the courtyard, so the street noise is not heard. (And if it were not, none could say about the street Lemercier that it is busy traffic)). Gas oven, microwave, refrigerator, washing machine, electric iron, clothes brush, dishes. In short, there is everything you need. However, sometimes I was missing the kettle. And the cover on the saucepan))
Owner.
I haven't met Gregory personally. We communicated virtually, but nevertheless, he is always in touch. Ready to help, to prompt, to advise. If I had to go to Paris again, I wouldn't look for other options.
