This is a gem in Rome.
The apartment is in a very old house but in excellent condition, all appliances are modern. Staying there really adds to the atmosphere of staying in Trastevere. The location is fantastic. Many, many bars and restaurants in walking distance and even just across the street. No problem with sleeping though as all bedrooms point towards the courtyard of the house.
The place is also a good starting point for exploring Rome. The Vatican is a 20 min walk, if you don't get distracted, same for Forum Romanum in the other direction.
Alberto was a perfect host, easy to reach on all channels (phone, WA, AirBnB), and very friendly and very responsive to any question.
