We've just got home from a week long stay and it was incredible. The apartment is perfectly located a 5 minute walk from Xlendi Bay (which is beautiful, has brilliant restaurants and amazing swimming).
Everything you need is in the apartment and is comfy (the bed is HUGE) and stylish. You do have to have €1/€2 coins for the aircon but we didn't spend more than €10 for the week.
Simon and Janina were brilliant with communication, always fast and helpful and the information you get before you arrive is better than I've ever experienced.
Also, Gozo is an incredible island, we rented a car and nothing was more than 30 minutes away.
We will be back as soon as we can and will be staying here.
