I stayed in this apartment for a week on my own. I really enjoyed my stay, it was just the right size for one. There's a lot of storage space so I was able to give a temporary home to all of my stuff. The WiFi connection is very good.
The neighborhood is nice: plenty of shops, boulangeries and cafés just around the corner. The apartment faces a school yard, so at night it is very nice and quiet.
My only critique would be that the apartment wasn't super clean. The bathroom (not shown in the pictures) has no ventilation and so it is prone to mould. I have a very sensible nose, so I act on smells, and it just didn't feel clean to me. Because of the slanted walls, sitting on the toilet is not very comfortable - I'm only 5"1 and could not sit up straight.
To summarize: great apartment for one, but I was a little disappointed about the bathroom.
