The apartment is very handy to St Pietro train station and walking distance to the Vatican. Federico is friendly and hospitable and gave us local tips such as catching bus 64 which we did find helpful one night.
He had good communication throughout.
We did think however that it would be good to have clear instructions on recycling. Maybe a few more basic supplies in the kitchen would be good and also a general spring clean!
Enjoyed staying there though. Good location, good host.
