First things first, 5 stars, no hesitation (more if we could)!
Our host Christian was amazing, met us on arrival, at 11pm, when he should have been at his cousins wedding! He was always contactable and always helpful.
The house was spotlessly clean, comfortable beds and cool, cool aircon... Its well appointed and has everything you need including a massive fridge/freezer.
The pool was lovely, again clean and refreshing in the heat. It's deep at 2.5m and we loved it.
As to Gozo, we loved it as well, we loved the swimming and we swam in most bays. Everyone is friendly. It's beautifully quiet and we never queued. We we ate out most nights and the portions are big, you could survive on one meal a day!
Gozo is one place I'd happily return to, as is this property, no question.
