We had an enjoyable stay at Gianmarco's.
The location is very good - close to the public beach, but a little walk into the old town. The apartment itself is clean, well stocked and has a pleasant balcony, but is perhaps a little basic. Fine for a beach holiday, but maybe not where you would spend a large amount of time indoors.
The best aspect of the stay was the welcome and the hospitality. Gianmarco's family were lovely and couldn't do enough for us. Gianmarco was very quick to respond to any request and was wonderful to deal with throughout.
