Our stay at Alessandra's was great! She welcomed us very warmly and made time to chat and give us advice about visiting Rome.
The loft is very nice. Very functional and clean. A microwave oven and a laundry machine would have been nice to have, but nothing that we could not survive without.
And we loved the bathroom and its green/blue color!
The location is also excellent. You can park your car for the night. You can then drive in the morning to Torricola Train Station (10 min), which is a mere 10 min from Roma Termini (the central transportation hub of Rome). One to two trains an hour, so make sure you check the train schedule before you get there (Google Maps/Direction helps a lot).
All in all, highly recommended.
