Jez's place is a very lovingly restored traditional building. It has all the facilities you need.
We didn't have any transport, but this did not present any problems as there are a number of bus routes within a 2-9 min walk, all going to Victoria where you can get connecting buses to other destinations. Victoria is a 5min bus ride or a 30 min walk.
For bread lovers there are 2 great bakeries nearby. One just sells bread the other pastries and bread. There are 2 local shops with in 25-35 meters or you could take a 10 min walk to Lidl. If you want a more authentic Gozo experience you could buy from the local mobile shop which announces his arrival to the theme tune from the Godfather.
Jez was a great host, alway got back to us promptly and has good knowlege of the area. Would definitely book again if we return to Gozo.
