I really enjoyed staying at Sara's . The location was great close to termini station. Sara was very kind and also very resourceful about where to eat around Monti. Few important info could be helpful
The house is converted to airbnb with multiple folks staying different rooms and sharing kitchen space. So it has a bit hostel feel. The apartment is also on 5th floor which can be accessed via stairs or very old elevator ( I believe this is already mentioned by others on comment section).
Overall I enjoyed my stay !
