Very lovely apartment. You are located in the middle of Victoria but it feels like you are in a country side house. Especially on the lovely front terrace (and you have three terraces down to boot!). There's also a grill there for lovely evenings. The apartment is clean, cosy and has everything you need (also, airco is present which is a must in the summer).
Reaching the beach is a bit far, but Gozo has some very nice places to swim (Xlendi is half an hour walk, the others you should reach by bus). The bus stop and any convenience stores are at walking distance (see the: country side house in the city remark).
As for the hosts, Mario & Marie are amazingly friendly people. They arranged a taxi from the airport to the ferry to Gozo and picked us up on arrival (and dropped us off again). They also had a nice breakfast waiting for us when we arrived (which we could really use with a 3AM departure time). They were very helpful and full of tips on what to visit and responded quickly to any questions we had before and during the stay.
All in all, great apartment and even greater hosts who really increased the experience and added to our stay.
