Andrea is an extremely warm and nice man who will make you feel welcome to Ostia once you meet him. His house is gorgeous and more comfortable than any beach house I've stayed at. On top of it, the location is perfect, only a stone's throw away from the beach, but still close to shops and restaurants.
The terrace is a huge bonus as well, enjoyable both during the day and night. I'm counting down the days before I can visit Ostia and stay at Andrea's again!
