Guglielmo's place was very nice and close to the metro. The only complaints I have are that the shower plumbing was not great, but I informed Guglielmo about it. Also, we couldn't find a sponge to clean the dishes before using because some were a little dusty. Guglielmo's place seems to be mostly safe. However, there were a few times when someone knocked or rang the doorbell and we felt it would be unsafe to answer. It happened once while we were sleeping and twice while we were getting ready to leave.
Other than those minor complaints, we had a fantastic stay and I would stay here again. Guglielmo is very nice and responds quickly. He gave me instructions on how to get to his place from the airport, which was very helpful. I recommend staying at his place and hope to be back in the future. I felt it was great value for the money!
