We loved our stay at Francesca’s apartment. It is really spacious with wonderful views and everything you need. We also managed to get around fine with public transport - a taxi from the airport was 15 euros, and the buses nearby were fine for getting to everywhere we wanted to go (a hire car would still be easier, but not essential!).
Francesca herself is an excellent host, asking in advance if we needed anything and even picking up some food for us to cook when we arrived. This made everything so much easier and helped us enjoy the trip even more.
There’s lots to see within walking distance; we enjoyed the blue grotto and Hagar Qim temples, and Qrendi itself is quiet and charming. All round a great airbnb experience, one of the best in fact!
