Simon and Janina are a very good host (who were keen to please and make you feel welcome and comfortable), and their place was quite nice - pretty much as described (so we concur with the other reviews). We didn't feel like we were away from home.
Xlendi (and Gozo as a whole) is a lovely place and worth visiting. Our overall experience was good, with lots to do and very good places to eat nearby. So if you are looking for a busy or quiet holiday, it offers both.
