My friend and I had a wonderful stay in Luca's room. This whole building is spacious and clean. And the room is even better than the pictures. It is very tidy and the private bathroom is very satisfying.
The location is awesome. It's ten-minute walk from Termini and 10-minute walk from the subway. Actually we walked to Colosseo once, it took like half an hour. We were always still out around 23:00 and the neighborhood is quite safe. A lot of restaurants and Gelatos nearby. Randomly choose one and the Italian food would never disappoint you.
Luca is really nice. He replies fast and is very helpful to give tourist information. The house rules are quite strict, but Luca emphasized the rules before booking, and it turned out to be a really wise discipline to keep the living environment good. I'm really sorry that my friend made some noise with hairdryer at midnight when I was not in Rome, but Luca reminded him not to disturb others. He is a very responsible host.
Overall, Luca's place, from every aspect -- location, service, room condition, cleanness, price etc., is perfect for staying in Rome. Definitely would recommend this place.
