Nice place, very well located if you plan a long stay and if you want to enjoy all what Malta has to offer. Saint Paul's Bay is a nice place and you are not too far from La Valette (without being in the capital) and quite close to the ferry to go to Gozo or Camino. Because of the trip we planned, the place was very central and it was a pleasure. We did not have the chance to meet the host but his father was very nice and answered all our questions. He also was nice with us, waiting for us when we were a bit late on our arrival, and being available quite early when we left. We were just a little suprised by the ecotax we had to pay (we don't think it was mentionned before our arrival), but it's only 50c/night/person.
Anyway, we have no problem recommending the place, thanks again !
