Stefano's place was overall very good.
The location is close to the Vatican, can walk there under 10 minutes. That means it's pretty close to a lot of other tourist sites like Castel Sant'Angelo, and another 10 minutes can take you to the Pantheon. As a result, the Colloseum is a bit further away. I arrived at Roma Termini and I wanted to challenged myself by walking to his apartment. It took my almost 2 hours but I passed by some great views.
The room is clean and most of everything works as expected. One of the shower doors was broken when I arrived. It could be closed but it took some more effort, was not a big issue for me. Hot water was great, not like some places where it runs out quickly. Bed is comfy and warm.
Interactions with Stefano was also great. He was a very nice guy and he lives with his family in the rest of the house. You will be able to hear them talking sometimes. I basically saw him once when he introduced the room to me and another when we both happened to be leaving the house, and that was it.
I highly recommend living here.
