This is a nice and comfortable appartment, very spatious (ca. 50 sq metres, two big bedrooms and a living room with a cooking space) and bright. It was perfect for our family of four (a couple and two small kids). Centrally located and close to everything, but still rather quiet in the evenings (we travelled in May). Second floor with no elevator, but we did not mind. Wonderful views from each of the three little balconies where we could relax after day of sightseeing. A washing mashine, wi-fi and air-condition worked very well.
Vito was a nice and helpful host. At the beginning we experienced some minor problems with hot water and sink in the bathroom, but he was immediately there to help and solved the problems. This was our first experience of travelling with airbnb and we hope all our future hists would be equally helpful.
The only thing that could be improved was kitchen equipment - it was indeed very basic. Fortunately we did not planned to cook, and Castellammare offered more than great selection of eating-out possibilities;)
