Sandro's nice, clean apartment is located close to the Vatican, and 30min walk from other main tourist attractions. It is quite large by European standards, in a a relatively modern building. It is located on the second story (European 1st), and there's an elevator for heavy luggage. We enjoyed use of a safe, dishwasher, and a cloth washer. Unfortunately there is no A/C or wifi. The apartment is located next to 2 mini-marts that carry basic necessities. Sandro accommodated our arrival and departure nicely, which we appreciated.
A few things that we wish would be improved: There was no water pressure in the showers, and we only had enough hot water to take half a shower / day between three of us. Also, one of the beds had a super-bare mattress -- we had a very hard time sleeping on it. Aside from these nuisances, it is a very good deal for a flat in Rome.
