We liked our stay in Lorenzo's place. Communication with Lorenzo was great before and after arrival. He was quick to respond, arranged a taxi for us from the airport and suggested a site we could use to leave our bags after we checked out including a discount code. We were also able to leave our bags before we checked in which was really helpful.
The place itself is in a great location for being able to take the bus or metro around the city and to visit the Vatican. It was also quiet at night and we liked the fact that it was in a traditional building with a beautiful old elevator and there was a lot of natural light but it was dark at night thanks to the shutters. Although we didn't use the kitchen much, it also seemed well-equipped with a kettle and coffee maker and cooking utensils. We saw that there was a washing machine in the bathroom too.
The thing we didn't like was the check in because the cleaner who let us in wasn't very helpful and it was difficult to communicate, even though we speak some Italian. When we asked her for some hand soap, she said there wasn't any so we weren't able to wash our hands when we arrived. Luckily we told Lorenzo and he arranged for her to buy some.
It would also be great to be able to pay the cleaning fee using the AirBnB app rather than having to have the cash ready to give the cleaner, but these are just small things and overall we would stay here again and I would recommend this place if you want to stay close to the Vatican.
