Nathalie communicated quickly at every stage of things--from the first inquiries, to making sure we could get into the apartment upon arrival in Paris, and checking in with us during our stay. The apartment is very well located in the Marais, a fast walk to the Metro and an easy walk to the Seine. Many good opportunities for grocery shopping (especially the Thursday and Sunday Richard Lenoire Market), grocery stores, fromageries and bakeries. There is a cute pasta shop/restaurant downstairs, you can get takeout before they run out in the early evening. The shop does occasionally have deliveries stored in the apartment entry, but it's not bothersome at all.
The apartment is up just one flight, and is represented accurately in the photos. Freshly cleaned, in excellent condition, decorated with some funky vintage finds. Comfortable living room furnishings, small though workable kitchen. One thing to note is (as pictured) that the eating area is a high counter with stools.
The bathroom is newer and works well, with a great shower. Plenty of good towels. We found the bed comfortable, and there was closet and shelf space for storage. As the bedroom faces the street you do get some street noise, but it's the usual city background, we didn't have an issue with it.
We had Parisian friends over for a drink one evening before dinner, they also commented on what a nice apartment it is.
