Cecilia's apartment is in the very center of Paris, only a few minutes walk from the RER train station at Les Halles or the metro. You can walk to many places in the center of Paris very easily from here. The Les Halles neighborhood is very busy, popular with young people. We chose the place for the location and the 2 bedrooms (our mid 20's daughter and a friend were supposed to be with us). Be aware there is no AC and no screens on the windows, so if it's hot you will hear all the (mostly) pedestrian street noise late into the evening. I felt that when the windows were closed it was very quiet (but I wear hearing aids during the day), my husband thought he could still hear street noise and wore earplugs to sleep. Apartment is reached by elevator to the 3rd floor (4th US floor) and then a small staircase up to the next level and the apartment. Building and apartment both very clean, well kept, and quiet. There are two real bedrooms with small double beds (one bed in each room), large sitting/eating room, separate well equipped kitchen, large bathroom with washing machine, and toilet room. Everything worked well.
