I spent 5 nights with my girlfriend in Maria's place. We have no problem to find it, because her son waits for us on train station and took us with car to theirs place.
Apartment was very nice and clean. All equipment looked quite new. We found there everything for cooking. Nice additional thing was espresso machine with some capsules prepared for us.
Size of apartment was enough just for two people. Big plus for balcony were you can sit and you have a lot of place for drying your clothes.
Apartment was located in some kind of centre of Santa Flavia. There is nice church on the other side of road. We found two pizzerias only few meters around. One small shop with bread and cakes right next door. It was only ten minutes by foot to train station and 30 minutes by foot to nice beaches on both directions. Place was some evenings little bit noisy but this can be solved by closing balcony doors.
Generally very good and professional accommodation.
