We loved staying at Marco's Beach Bar. The area is casual which we liked. Easy bus ride to Termini and other connections or you can walk. We walked to the Colosseum even (30 mins). Rome is a walking city so bring comfortable shoes!
Wonderful beds in the apartment and very well equipped. A real treat to spend time here. The stairs are fine, we had no problem with them. The kids liked counting them as they went up and down.
Would definitely return to this apartment. Thanks for having us Marco.
