I was in Paris for four nights and this was a perfect location in Les Marais! The space was fine, it's about the size of a normal hotel room, and the pictures convey it well - it was what I was expecting. It did get warm, but a fan was provided.
The location is really the highlight of this apt. There are tons of great places to eat and drink around the area and it's really close the Marché des Enfants Rouges (amazing market).
My only improvement is with the amenities. Toilet paper was not provided, which I think should be. I was expecting it, so I didn't bring any, but luckily there was some already there from other guests.
The place was pretty reasonably priced though, and other than that, the location is amazing and I had a great time. Benjamin was also a great host who responded quickly to all of my questions and messages. I would definitely recommend this place.
