My stay at Yosr's apartment was wonderful. I highly recommend staying here.
The flat is (compared to Parisian standards) really big and very clean. The kitchen was fully equipped. Within short distance, you'll find tons of bars, wonderful restaurants, boulangeries and the best fromagerie I've ever been to. The 11e is quite "non-touristy", which I loved. On the flip side this means that it can be loud on the streets until around 2:00 am. When you close the windows, it is, however, really quiet. I even slept with fully open windows and did not wake up often.
You'll also find a lot of velib-stations nearby, so you can rent a bike and be for example at the Louvre within 20 minutes or you just take the metro from Parmentier.
I loved it here!
