Mattia's place was great. The rooftop was a nice way to spend the afternoon to escape the craziness of Rome. The location is great with all kinds of restaurants and bars close by and fun streets to get lost in. It's very central to all the sights too. The host had a friend meet us with a key and very informative instructions. Make sure you have wifi or cell service to stay in touch because there is no lockbox. It worked out fine for us. The place is is great. The only thing to keep in mind is that you have to go up about 6 flights of steep stairs and the elevator is out of order. Not recommended for the elderly until they fix the elevator. But it's a small price to pay for a great view. No complaints here. We had a great time!
