This is a lovely and very stylishly decorated apartment. Everything was as advertised - very close to the beach and within walking distance of anything you might need, including the charming town centre with plenty of shopping and eateries (closed to vehicular traffic after 7PM).
If you go during the hottest months, however, be prepared either to pay quite a bit extra to use the air conditioning units (as specified in the listing) or to be very hot. There are ceiling fans and table fans throughout the house, but because of the close proximity to the sea and the fact that roof is almost entirely exposed to the sun, the humidity and heat is pervasive.
The only other (slight) drawback was the refrigerator. It fits very nicely in its spot in the beautiful Sicilian style masonry kitchen, but it is an office-sized fridge with only a very small freezer compartment. Even at the highest setting, to chill a bottle of room-temperature water, you'll have to leave it in overnight, but it does work properly for its size and intended use. For 2 or 3 people, it would probably be just fine, but considering the fact that the flat can potentially host up to 8 guests, it is something to bear in mind.
I've save the best for last, of course: Julia and James live in the flat upstairs with their beautiful Chocolate Lab and they are extremely hospitable and friendly, always quick to reply to any questions or needs you might have during your stay!
