This is a small, quiet apartment on the second floor (the building does have elevators), reasonably priced and well-suited for one or two travelers. It is located within a few blocks of multiple metro lines making it easy to get around. There are cafes and groceries within easy walking distance, and a very small market right outside the front door to the building. The neighborhood seemed very safe, and building security was good.
We enjoyed the balcony patio, which offers a lovely, peaceful spot to relax over morning coffee or an evening drink. The host is very quick to respond to any question, and the communication was very clear, which made the reservation and check-in process quite easy.
Like many Paris apartments, there is no air conditioning. Opinions will likely vary, but we found it to be quite warm if the outside temperature rises above the low 80s F (above 27 or 28 C) during the day--fortunately, that was really only one day during our stay. The sliding door to the balcony provides the only ventilation and we generally had it open all the time when we were in the apartment.
