We didn't meet Gianluca but he was very helpful & kind to give us all the info we need before our arrival. He was very responsive & precise in his answers. I believe it's an apartment especially arranged for Airbnb.
The studio is quite nice & very close to the metro (line A). However, the apartment is not close to sightseeing attractions which can be a good thing to relax after a long & hectic day going around Rome.
The neighbours can be sometimes loud. So, we had to close the window in the morning.
You can have some mosquitoes but the windows are prepared with a "moustiquaire". So, don't forget to use that.
The apartment was very clean & we had coffee, tea, etc. for free.
There's a big supermarket that's open 24h.
We had to leave the apartment quite early @9am. So, be prepared for an early check-out.
