Josephine's house is really amazing! It's very big, has all the amenities you'd need and has a really nice outdoor place with a pool and BBQ.
Contact with Josephine was very pleasant. She lives a couple of houses down the road and made sure everything was okay and gave us a lot of advice for good restaurant.
The house is at a short driving distance to all the places you'd want to visit in Gozo. The village itself is small, but there a couple of supermarkets at walking distance (longer walk though).
We think this is the perfect house to rent in summertime. We were there in april and unfortunately the house was very cold (despite the coin operated A/C we used for heating), also because the middle of the house is an open courtyard (which you walk through to go upstairs. But most likely this is a very welcome feature in hot Malta summers :)
