We know Xlendi. We were lucky to find a reasonably priced flat during high season. The pool was perfect for getting our 10 month old baby used to water, and also has a spectacular view of the cliffs. It's a bit of a steep climb up from the bay to the house, but not impossible.
The flat itself was great for relaxing and having breakfast/dinner on the terrace. It was too hot on the terrace in the day. Inside, the fan provided enough air to keep us cool at night without A/C. We were able to prepare meals just fine, though there is a lack of cutlery (only 1-2 of each). There is no daily cleaning, but we were able to get new sheets when asked for.
The only major downside of this flat is lack of a clothes washer or a service to do it. There are no self-service laundromats in Gozo, and it cost 20 euros to have a small batch of clothes washed (without drying) by a service in Victoria.
Manoel and his team are very hospitable and correct. Recommended!
