Paola is a fantastic host, very responsive, very helpful & generous. The house was comfortable. It's on the third floor and there's a lift which is really good after a long day. Though it was out of order a few times.
The house is walking distance from Roma termini and hence close to public transport, even the Colosseum. Location is great.
Though the neighborhood is disappointing to be honest. At night it gets uncomfortable. The streets are lonely, with lot of homeless people. We saw someone urinating outside the building, it's quite dingy. Though it might just be this way for me and might be ok for others.
