Matteos apartment is a cute and very centrally located place in Castellammare. It has everything you would need and Matteos and Clara's outstanding hospitality was a plus. It is in a carefully renovated old Sicilian house on the top floor, so you get mountain and sea view. But everything is very small and narrow, so you shouldn't be extremely tall or have impaired mobility. The streets are very narrow, but you can park for free right in front of the apartment. For us it was perfect because it was very close to places we wanted to visit and has lots of nice bars and restaurants close by to spend the evening. If you are reliant on a stable wifi connection, it might be worth to check beforehand with Matteo, since there were problems with the antenna during our stay. For us it was not a problem at all though.
Highly recommended!
