The apartment is a beautiful place that was perfect for our family which included my wife and I, our three year old daughter and my sister. It is in a good location for getting around Paris with the Bastille train station about 5 minutes up the road and the recently renovated Picasso museum just a 15 minute walk. There is also a grocery store right around the corner which was great. The most impressive thing about the place is that you enter the gate off this main road and you are on a quiet cobblestone road walk up to the apartment building. Once you enter the place, it is serene and you could think you are in a quiet French village rather than the middle of Paris. Only downside was the walk up the 4-5 flight of stairs with the suitcases but I think this is hard to avoid in Paris. This was balanced with the fact that we could leave our daughter's stroller on the ground floor.
Anna was very helpful and was there to check us in. She always responded to queries within a couple of minutes and was kind enough to order us a cab to the airport when we checked out. All in a great experience.
