I stayed 3 nights. I can definitely recommend it and would come back.
Check-In/-out was super easy and flexible. I stayed in touch during the whole stay and even after my late arrival I had a very friendly welcome.
Before leaving I just had to empty the bin and left the key on the counter.
Area is nice although I haven’t been strolling around that much. Found a really good bakery next to the supermarket which is just a couple of minutes away. The metro station of M11 is right across the street.
The apartment itself is typical French I would say. Many small rooms in kind of a row and high ceilings with typical French stuck on the corners. My room was as described. I like a good harder mattress and it was calm so perfect for my sleeping. WiFi was working perfectly as I was working there during the mornings.
Only thing I did not like that there was a little too much dust in my opinion but can be easily removed for the next guest.
Overall wonderful easy stay. Just what I needed.
