Great place for a great value. Slept 5 people and the living room is a little tight to all hangout in. Rooftop terrace was a great addition but very hot while there. Would definitely recommend. Close to cafe and market. Also close to a taxi hub which was convenient. We walked to Colosseum (just under a mile) and pantheon/trevi/ Spanish steps. Did have to taxi to Vatican. Everything is within a mile-ish. They were very responsive and accommodating. Large closets to hang clothes which was nice.
Stair case is open as other reviews stated. If afraid of heights or have children I would not recommend but nice to have split level for privacy
