Lots of great things about this spot, but overall for me the location was the best. The street is populated by apartments, but it is very quiet at night and well lit. About a 15-min walk in one direction and you're at the entrance to the Vatican. 10-mins in another and you're at 3+ really great restaurants/cafes, a large-friendly bar and small bodega. Uber to the Coliseum or train station is about 20 euro. The incline to the AirBnb is nothing crazy either; you barely notice it.
The space is much larger than I expected. Massimo utilizes furniture and décor very well to where you feel like you're walking into a vacation home and not just somewhere to sleep. He offers surround sounds, bottled water, some non-perishable foods, everything to cook with, etc. 3 adults were staying here and we never felt like it was crowded. Plus with the windows open, the temperature stays perfect and there's security windows to keep you safe.
Even checkout was great. Massimo's assistant, Salvatore, stayed with us to ensure our Uber pick-up was fine. There was a bit of confusion, with the driver, regarding which level of Uber we should've requested. Salvatore resolved it and we were on our way to the train station.
Fantastic time!! Wish we could've stayed longer.
