Bastien’s place is perfect if you are arriving from the airport, as the train from the airport connects to Chatelet (2 blocks away from Bastien’s place).
The apartment is perfect for a couple or a group of 3 people, and is fully equipped so its good for a short stay and a long stay.
Only downside is that the apartment is located in an old building, so you need to be prepared to climb 6 floors with your luggage (no elevator).
I totally recommend this place!
