The apartment is in a great location. It's in between two wonderful parks, close to Metro 11, on a quiet street. It has recently been remodeled and everything works. Most things are new, from the Ikea dishes to the new window fittings to the Paris posters on the wall. The building contact is on the same floor and simple to connect with. She also is very hospitable and able to help with practical things. The building is very quiet and well taken care of.
Everything you need to buy is available within a couple of blocks of the apartment. Belleville is a great area, and Metro 11 gets you to the Pompidou Center, the Marais or Notre Dame in a short ride with no stops. Belleville itself is a fascinating quarter with many things to explore.
