Location: next to station so easy for public transport. A bit far from main attractions if you want to go have a quick look (+-25 minutes to go to colosseum, pantheon, etc) but you can easily take public transport if you don't feel like walking there.
Room: it's a perfect stay if you're planning on being out most of the day. Comfortable and clean. You do hear other people in the hallway but it's not that distracting.
Service: hosts dad was there for the check-in. He's extremely friendly and helpful.
