Great location in Trastevere, from where you can walk to all attractions. The regional train also stops in Trastevere so the Fiumicchino airport and the west coast beaches are very easy to reach.
San Fransesco's staff was polite and helpful, and our room 102 was quiet and pleasant, jet small.
The breakfast was good - white bread, eggs, cold cuts, fruits, yoghurt, cereals, sweet pastries, delicious juices and coffee etc, and the personnel seemed to take allergies and special needs in consideration well. The roof terrace was nice and the hotel's original, italian style was attractive too. Room cleaning worked effortlessly, likewise the air conditioning! The only con i must give is having just one large blanket for the couple in the bed, we had a little difficult getting used to it - didn't ask for our owns though.
All in all, we absolutely would recommend this hotel!
