We stayed at Domus RomAntica for the last leg of our honeymoon trip in Rome and it was a delightful experience! The downsides, which I'll list first, are the room was a bit small (the bathroom door blocked entry while it was open), the bathroom didn't have much counter space to place anything and it was a little dark inside the hallways. However, the front desk was very friendly, it was quite cozy and comfortable, the ceilings were very high to help make up for the smaller quarters, the vouchers to eat breakfast at nearby affiliated restaurants were a nice touch, and it certainly was a romantic experience. Bonuses were there were a few top rated pizza and gelato restaurants nearby.
We will definitely stay here again should we visit the same area in Rome again!
