We arrived to Casa Ro late in the evening with our 3 children. Roberto welcomed us on the spot, communication was easy with him. He helped us settle, gave tips, arranged for the parking, even bought us milk in that late hour for the next morning - excellent hospitality. Check-out was equally easy, and we got some farewell sweets too :).
Location was excellent, strategically positioned for a stroll either to the sea's direction (with park and playground) or into the historic centre. Restaurants, bakeries, shops are around, parking in nearby piazza Marina is free of charge (just tip the guy aiding there).
The apartment is located in the first floor of a centuries old building which definitely has a romantic factor but don't expect 4-star hotel standards when it comes to practical layout, water pressure, or acoustic insulation (though the narrow street it looks at is not noisy). Also, the apartment is a bit worn as compared to the pictures. Since we hardly spent any time there apart from sleeping, this didn't bother us too much.
Overall, very nice host, great central location for an affordable price.
