I can' share the enthusiastic reports of the previous visitors. Once the couch is prolonged there is rarelay space to move., one stool to sit on and one cup is not sufficent for two people. One of the cupboard side is stuffed with leftovers of other people, partly dirty and sticky. The elevator to the flat is poorly mended, is only suitable for one slim person. If you take the stairs, you have to pass half a floor in the dark before you reach the next light switch .
As we were the only vistors at that time, it was quiet. The surrounding is quiet, the flat is nearby a metro station, an there are some bakeries and supermarkets around.
It may be that the flat is cost-effective for Paris, but we have seen better things and will surely not come back..
