The property at 504 Corso Suites was excellent! It is in a fantastic area of town, walkable to every site if your in decent shape and safe, with TONS of shopping and dining options everywhere. Katerina was on concierge who met us at the property to help us in and show us around - very friendly and informative!
We were affected by an airline stike before the end of our visit and accomodations we tight, but another attendant at the property, Micaela, went above and beyond at the last minute to secure us a room at one of their other properties, only 2 blocks away, for a family if 4 for 5 nights. Micaela even walked us and our bags (literally down the street) to our new location for an early check-in, and helped us get settled, I couldn't have asked for a better outcome in a tough situation.
I would recommend this and any other property, operated by this group, to anyone travelling to Rome; hands down the best service experience we have ever had travelling.
