Thank you Carlo and you your son for letting us stay with you! They were very accommodating with a late check in (we were more than happy to pay extra for this service since they have to stay up to let you in) and also by letting us keep our bags there for a couple hours. It’s a shared apartment and is less than 15 minutes walk from the Colosseum. There are a lot of scooters in the city so anything that wasn’t walking distance was an easy ride away. Thank you Carlo!
