I did not enjoy my stay at this apartment. I booked it for two months, but only stayed for one week. It might be fine for you if you're coming for a shorter stay and plan to be out all day. But I think it's unsuitable for a longer stay or if you need to do work from the apartment. I found it to be quite uncomfortable and unpleasant.
The apartment is quite dark. It's on the first floor, and there is just one window in each room, and there is another building across the way, so there isn't much natural light.
The apartment is also not very homey/cozy. It's fairly minimally furnished. It sort of feels like an empty place that someone threw some cheap furniture in. I found all of the furniture to be quite uncomfortable. The bed was hard. The dining chairs were uncomfortable. One sofa was uncomfortable, and the other one had a weird smell. The kitchen was not very well-appointed either.
Riccardo was very responsive when I asked for additional supplies during the week that I was there (a knife bigger than 3 inches, converter plug for the coffee maker, hangers, etc.). However, I found him to be quite rude when I informed him that I wanted to leave early. He did not allow me to modify the reservation, and he called me disrespectful and said that my complaints were unfounded (sir, I think I know whether or not I am uncomfortable!).
Overall, staying at the apartment was a quite unpleasant experience.
