Nice accommodation for a big ammount of people.
Its behind the vatican on the not touristic side so its a walk of about 20 minutes or a short ride with the Metro to reacht the tourisic center of rome.
We stayed about 5 nights in the accommodation and had no problems with our stay.
The check-in works with PIN. Federica is available via Whatsapp or AirBNB for contact and cared if we had any problems.
