We've stayed in this hotel 4 nights. Very quiet neighborhood, very close to malakoff metro station (you can get to central paris in about 30 min.) and there is a market on fridays and sundays.
Cons: Hotel had no elevator so if you have a heavy luggage you might have to take it as 3 stories high, and the climb is pretty steep. Also if you get the room with widow to the garden you get all the smoke from people smoking underneath. The room we got was very very small, except for a double-bed there was not room for anything else, we even weren't able to open both of our suitcases at the same time. All furnitures were old. Finally, when we arrived we had to pay tax for the city, which was a scam IMHO.
Pros: Close to the city central, there is a metro about every 5 minutes. Helpful staff though their english was so-so. The bathroom was new and very clean, so were our sheets which were changed daily. In conclusion, if all you going to do in the room is sleep this hotel is OK, but then again, maybe there are better choices only for this.
