All in all we had a nice stay at the appartement and I recommend it :)
We didnt really use anything besides bed and shower, since we where gone all day and where eating out. But we enjoyed the music box that connects to your phone while getting ready :).
The appartement isnt far from the trainstation, that was nice to drop off the bags right away and head out to discover paris without loosing much time.. :)
Although we couldnt do the check in personally, so we went to the store where we thought to get the keys..but the guy sent me away to another store so we were walking around a while trying to find the right store..ending up going back to the first one since the explanations cleary lead to that one.. I explained again what I was looking for slowly and with gestures so he finally understood and we got the keys :D
Once we had it everything worked out fine :)
There is a nice big Park to walk through next to the appartement and bakerys with delicious croissants etc. for a nice breakfast.
Thank you :)
