Great location! Extremely close to the Abbesses metro stop which was easy to transfer to several other lines and get to all the sightseeing destinations. There are cute bakeries and restaurants in the area and a little grocery store at the next corner.
Check in and out was extremely easy and convenient since we arrived early in the day and left later in the afternoon.
The apartment is very tiny but completely doable for a couple and fairly comfortable. The sofa bed was actually very comfortable. We ended up leaving it open for our whole stay but it was very easy to open and close. My only complaint is that we found the dishes, glasses, and mugs to be not washed throughly but we just washed anything we needed before we used it.
