We travelled in a group of four women. The appartment is absolutely great: fabulous views in two directions (Sacre Coeur or Eiffeltower), cosy rooms, everything very functional. We loved the provided slippers and huge TV with some nice DVDs. Bedsofa works well.
Communication with Ismail was very easy and quick.
Beware: The elevator is quite small, can hold one person with one (not too large) suitcase ;)
Would totally come back here!
