We didn’t meet Roberto but his partner Francesco. He was there timely, he was kind and very helpful. The house is cute, perfect for 2 people but not more. The location is great, 5 minutes walk from the metro , 5 minutes walk from Vatican and 25-30 minutes walk from the historical center. Also, the neighborhood is nice, you can find good restaurants and super-markets and it is very quite during the night so you can have good sleep. Wi-Fi is very good as well. The bathroom is small, not so clean and the shower box is extremely tight. The bed is not exactly double but kind of 2 single united and the bed base is quite destroyed. Overall, we stayed 3 nights and we really enjoyed the apartment in spite of the 2 issues with bed and bathroom. For more days those 2 things would be a problem for me.
