Luca's place was clean and spacious, and was located right in the middle of most of the places we wanted to visit during our stay, but far enough away from the tourist crowd that it still felt like we were actually among locals.
The place was fairly close to the train station too, and within reasonable walking distance to Trevi Fountain, The Vatican, and The Spanish Steps.
Luca provided us with a list of recommendations for places to eat, and several cafés and gelato places were located just outside the apartment down at street level.
This was our first airBnB experience, and it was an excellent one. We'll definitely be trying it again for our next trip.
