We spent one week in San Felice Circeo in June 2018 and really liked this place. Great beaches (especially the 30 km long one between San Felice Circeo and Sabaudia), a lovely old town and a harbor with restaurants and ferries. Not too many tourists. We took the speed boat to Ponza one day where we rented a boat of our own. Such a fantastic island! Do not miss to go here! The apartment is very clean, very nice, and with a fantastic garden as well as a terrace with a sea view. The villa is situated 10-15 min from the closest beach, 10-15 minutes from old town and 10-15 minutes from shopping street with shops and restaurants. Gabriella, the owner, is very friendly and helpful and speaks great English. We really appreciated the fact that Gabriella has prepared for our arrival with leaving some toilet and kitchen paper, soap etc for us and even prepared cold drinks in the fridge and some snacks! Thanks a lot Gabriella , we really appreciated this after spending the whole day on airplane and in the car!
