The place is very small and has no windows for fresh air (it looks more like a garage) which brings a bad smell to the place. The hot water is limited, but it was enough for 2 persons. The door has glass windows which is very unsafe and we also had a bad experience where a homeless person decided to sleep right next to the door.
You can hear everything through the walls, from people walking to talking on the phone. The place is very close to colosseum and to subway station. Frederico is a very responsive host and helped us with everythig we needed. If you want stay here for just 2-3 days, the experience is ok. If you want to stay longer I will recommend to look for something else.
