Most of all, Joe and his wife are very friendly and responsive people. They told us a lot about interesting places to visit and maltese festival during our stay. Transport from the airport to the apartment is optional and costs 25 extra euros. Every problem we had (how to use a washing machine/need of electric adapter from british standard) was solved within one day.
Apartment itself was cosy and had everything we needed. There is enough space for 4 person. Lack of air conditioning wasn't a problem for us. Bus stop as well as supermarkets, town centre, restaurants and church were rather close. It would be hard to reach closest beach by foot, but public transport makes it easy to reach any place.
