The contact with Pierre (or agency employees on his behalf) was very good - we received the information how to get to the apartment or make self check-in (we arrived late at 10pm). However the provided instruction was not clear and not correct so we had a problem to localize the locker to collect keys. Additionaly at the beginning we had a problem to get in to the building (the instruction stated use the key to main doors to the building but there was a code not the key) and as we finally got in there was no electricity in the apartment. Although after couple calls to the person provided as emergency contact around 11:30pm we finally were in the apartment.
It was stresfull especially during Christmas night.
The apartment is very nice decorated and functional, very well located in beautifull area. The facilities are enough (hair dryer, plates, iron and so on). The bed (coach) is very comfortable (we were surprised that coach can be so much comfortable to sleep! We really enjoyed the design and furnitures of the apartment. It's on of the best apartment we stayed with airbnb.
There are couple cons as no microwave or oven and it was not clean so as w got up next day morning we had to make a cleaning on our own. The was not tea or coffee and soap to wash dishes, what would be nice to have but it is not a problem you can buy it (as we did, so the next guests will have tean, coffe, soap and snacks :-)). We also received only 1 towel per person for whole week which is not enough.
Staying in that apartment you should take into consideration that floors are very thin and neigbours are bodered by you just because of walking. But they are extremely nice and positive attitude people and we enjoyed their visit and being so nice that they even offered their help to give us a tips where to eat, what to see and so on.
Summarizing we recommend the apartment and will stay the againg when visiting Paris.
