The location is absolutely excellent. We could walk to almost everything that we wanted to access. For things that are a bit further, or when you've been on your feet all day, there are innumerable bus and metro lines in the neighborhood.
Daniel's communication was always excellent and prompt. When we asked whether we could drop our bags somewhere after our early morning flight arrival, he responded by offering to meet us at the apartment in the morning for an early check-in and he even brought us breakfast from the boulangerie next door!
We were in the heart of a lively neighborhood, but the bedroom is in the back of the building, away from street noise. One of us is a very light sleeper and had no problem. If the living room is used as a sleeping area, then the street noise may be a problem at times of year when dining patrons are outdoors.
We had a wonderful week in Paris, and one of the main reasons was the location and comfort of our accommodations.
