Alex & Olivia were very nice and always available. I can only recommend them as hosts. The apartment is very well equipped for a longer stay and has everything you need. A laundromat is right around the corner. In addition to that there are four metro stations (6, 10, 8, 12) and numerous bus stations reachable within a 5-10min walk.
The apartment has the perfect location if you are studying in Paris. I would definitely stay here again.
