Holy is a very friendly, uncomplicated and helpful host (thanks for helping me carrying my heavy luggage in the stairs!) The apartment is simple and personally decorated. It’s on a busy avenue but there’s double glass and the traffic gets quiet at night. Also there’s good shades so no light comes in from outside in the morning (but the doors inside the apartment are partly glass so you could see light from the corridor). The sofa bed is ok for a couple of nights. I would recommend the apartment for animal lovers as a friendly rabbit lives in the bathroom, turtles in the kitchen, etc. It’s close to Trastevere Station so it’s distant from foodie/nighttime “hip” Trastevere but very convenient to get to Fiumicino airport.
