Gael is an excellent host: available and helpful.
We had the room #4: clean and minimalist, perfect for us.
The place is very well located in a quiet street.
Main sites are all within reach, we did everything on foot: Trastevere, Monti, Piazza Navona, Villa Borghese, Vatican.
If you wish, all kinds of public transportation are very near (train, metro, bus, taxi).
We recommend 100% this place.
