I absolutely recommend Mary's apartment! My wife, daughter and I stayed for a week in Rome and had a wonderful experience. The location is fantastic, and the apartment was charming, spacious and comfortable. We loved that the two bedrooms are on opposite sides of the apartment, and that there ware two separate bathrooms.
Communications were excellent throughout the process. Mary and her team are super responsive. Cristina was amazing! She helped us several times to answer questions, quickly resolve some minor issues and assist us with transportation arrangements. Next time we are in Rome, we would be happy to stay here again.
