Booked the house for a family trip to Paris and we had a really great time. First of all, the check in experience was really smooth and quick, the host was also very friendly and welcoming, answering all the questions we had about the house and the area. The place in itself is a small apt but it offers all kind of comforts for a nice stay. The location is amazing and probably the best thing about the place: close to a very well connected station (Grand Boulevard), 10 minutes away from Chatelet-Les Halles, bus stop for n. 85 (the one that takes you up to Montmartre) right in front of the door. There are supermarkets nearby and the street is busy with all different type of options when it comes to eating out. About the last bit, even if the street can get really crowded (especially on the weekend) we had no problem sleeping well.
The only thing I would suggest fixing is the bathroom' door, it basically doesn't close very well and if you want to use the bathroom with full privacy you're forced to close the main bedroom door to make sure no one can see you from the other room.
