Emanuele's place was the fifth in our tour of Italy (Rome->Firenze->Venetia->Tuscan Countryside ->Rome). We took the option of using the third bedroom (extra fee) because our teenagers are used to sleep alone.
First, Emanuele's reception was probably the nicest we've ever experienced (and we have had great experiences overall, including in this Italy trip): He was there on time (thanks to preliminary chats adjusting times as we ran into a delay), gave us a thorough tour of the premises, and a host of useful suggestions for visits, transportation, and eateries.
Second, the place was immaculate, and very practical. It's most clearly adapted for a stay of up to four people (which was our party size), but it could handle more if needed. There is a "bar seating area" for four in the kitchen, a table for four in the small dining room, and that dining room also has a loveseat for two. In our case, we actually had three bathrooms, which is extremely nice to get everyone ready for our daily adventures (we usually aim to have _two_ bathrooms when possible; _three_ was just icing on the cake).
Emanuele's apartment is within walking distance of Vatican City and we had planned our visit thereof based on that: It went perfectly. Some other places benefit from transportation, but thanks to Emanuele's advice, that was not a problem.
Highly recommended.
