(+) The appartment is well located, lots of shops nearby, walking distance or metro to almost everywhere. The bathroom is refurbished and almost new. The appartment is not extremely big but good for Paris. Check in and check out is easy (codes and so on).
(-) For two days the hot water didn't work (but finally it was settled), and some minor details should be repaired (ej. chairs) Once you're in the apartment it's clean and fine but there's no elevator and the staircase is quite old/steep.
