I came in November - it was like paradise. Zero degrees in Germany - 2 hours flight - over 20 degrees here. And the guesthouse, wow! The garden wow too! Oranges, olives, lemongras and other well smelling plants. A secure place for my car in the area, behind the gate. And all this crowned by very nice owners (and a nice, cautious dog - even if you don't like dogs)! I can suggest this place.
Only: It's a few kilometres to Marsala centro. The trainconnection is bad, if you walk, its uncomfortable along the road with many cars.
