Valerio's apartment was clean and had everything we needed. Location-wise, it was walking distance to many sites or at least the corresponding bus stop. We felt safe and slept peacefully. The only things were the washing machine and living room TV weren't in operation, but it didn't affect our stay.
Valerio himself was patient and prompt with our check-in and check-out. He was helpful with maps, and texting communication to answer any of our questions. He even welcomed us with a gift of pasta/sauce, cookies and juice/water!
Overall, a great stay, a great host!
