It is a fantastic, well thought-out and stylish place! The location is very nice as well. The hosts are very kind and thoughtful (they even provided toys for our baby) and helped with additional services that we needed (taxis etc.). The house itself is very pleasant to stay in, but do take the "small luggage" advice seriously as the steps are very narrow and steep (nothing uncommon for such places, I imagine).
Would definitely recommend to anyone flying out there to check out what Malta (and Gozo) has to offer.
