We had an amazing stay at Fabio's apartment. Ideal for 2 people. Very neat and clean. Quiet as well. Has all the basic stuff one might need. There is a balcony. The wi-fi is fast. Nice things like board games and books (all in French of course). The location is great too: two subway stations nearby (10-15 mins ride to central areas), plenty of food points, a grocery store, etc. A lot of various shops on Rue de Tolbiac.
Although I haven't had the chance to meet Fabio in person (yet), the communication was great.
Some minuses to be fair: the shower is pretty small. There was only a single proper large blanket (duvet) for the bed. (I prefer smaller separate blankets). And that is probably it.
I definitely recommend this place.
