Nice place,convenient location next to subway,walking distance to everywhere. Place does not have reception with someone 24/7 there on a desk. You have to confirm your arrival time,so someone will show up and give you the key.
Hotel has no elevator, so if you are not able to bring your suitcase on a 2nd-3rd floor,that place is not for you.
Breakfast is good,right across of the steer in the restaurant.
I would come back to Rome and stay there again.
