Luca's apartment is great, very well placed (10 minutes from Colosseum, 5 minutes from basilica Santa-Maria Maggiore), clean and has all the conveniences needed. Luca himself was very nice and helpful, he gave us some good advices for visits and restaurants and made all for make our stay comfortable.
It's a perfect place to stay in Rome, and I will return there next time if I am in Rome. Thank you, Luca!
