Pros: Great location, easy walking distance to Coliseum, restaurants and COOP (grocery). Interestingly, it's on the edge of Chinatown. The apartment was very spacious, well-maintained, clean, and well-stocked with several coffee making devices, pots/pans/glasses/silverware, etc. Plenty of hot water for showering.
Cons: We messaged Renato in advance that we would be arriving a little early, and even messaged when we left Siena with exact arrival time. Originally, he (which was also misleading since it's a woman's photo in the description of host) said we could drop our bags, no problem, and leave while they cleaned the apartment. When we arrived, no one was home. We walked into the building to try knocking on the door, and a little old woman chased us down, yelled at us, and literally escorted us out the door of the building! Unbelievable! We had 2 infants (5 months and 11 months) and were shoved into the hot street with all our luggage. I've never been treated so rudely in my life! I'm guessing she is the super or building manager, but every single day we entered and exited, she came out of her apartment to yell at us about something in Italian. Even when we were checking out on the last day, I left 2 bags near the door while I returned to the apartment to get my baby and she pointed to my bags and said I needed to get them and leave immediately. If you're going to rent your apartment on Airbnb, maybe you should tell the people in your building to NOT be so rude to your guests. After calling Renato again, he said we should just "relax and go to a bar". Yes, with 2 infants we should just go to a bar.
Finally, when we could check in, a nice cleaning lady let us in. However, we soon discovered the air-conditioning in the second bedroom was only blowing warm air. Again, we called Renato and he said "Sorry, we haven't gotten around to fixing it and the repair man couldn't come for another 2 weeks". Well, that would have been good information to know ahead of time!
In addition, the apartment above ours was undergoing major renovations, so every morning we and our infants were woken up early to the lovely sound of hammering, jack-hammering, drilling, etc.
I don't like to leave negative reviews, and your experience may vary, but overall we were very disappointed.
