We really enjoyed our week in Samy's little appartment. It is enough for 2 people and it had everything we needed during our stay.
Communication with Samy was great, he even allowed us to drop our luggage in the apartment before the check in time, as we had an early flight.
Location is fine- between metro lines M4 and M12, so we were able to easily reach all necessary places. And there are a lot of nice places in a walking distance too, like Montmartre.
The street outside might be a bit loud, as bars nearby are open until 2AM, but the windows were surprisingly great- there's a total silence when they are closed! :)
