We were very happy with our stay here. The hosts were very kind and helpful. The pre-travel communication offering pictures of the entryway and how to find the apartment was especially helpful. The space was very clean with all the modern amenities we needed. It was also quiet with windows opening up into an internal courtyard. It is a small space, which we were expecting, but it's worth noting. We travel light, backpack and duffel. If you travel with large or heavy bags you will need to get them up one flight of narrow spiral stairs, but for us, this was not an issue.
We really enjoyed the location. There are great wine bars, cocktail bars, and restaurants just a few minutes walk away. We also easily walked to the main attractions near the Louvre. It is a longer walk, 30 minutes or so, but if you enjoy being out and about like we do, it was an enjoyable one. If I were traveling alone, I wouldn't hesitate to book this flat for an extended stay. For two people, it worked great for a few days in Paris.
