The apartment is very well located, right beside the Notre Dame, very centric and turistic places all around - really recommend it if you have few days to go around Paris.
It is all remodeled and confortable, everything works well in the place. The bathroom, kitchen, heater, all great!
The only comment is it is a small place (very very common in this region, so nothing too surprising), and the bed is a sofa bed, but works really well and is comfortable.
