When you come to Gozo, from Mgarr port, take bus 303 and get off at the Guzepp stop in Qala ( almost in city centre ).
Walk towards the city center and turn right at the first street ( pic 1 )

Continue straight, and after a few meters, turn into the alley on the right ( pic 2 & 3 )

Walk to the very end of the alley ( pic 4 ). Your house is the last one on the left ( pic 5 ).
