This place is located in the very heart of Trastevere. Walking distance of EVERYTHING. Surrounded by great restaurants and cafes. Go visit Mammos ( 50 feet from front door) and Donkey Punch ( around the corner). The three terraces the flat has are amazing. Beds were super comfortable. Our trip included 5 people and we had plenty of room.
Just as an fyi the stairs leading up to the door are typical of classic, old Roman buildings. Very circular, concrete and steep. We were fine but not for people who struggle with mobility.
