This is best airbnb experience ever.
Caterina and her mom was very helpful to me, accompanying me to nearest beach(3 min by foot!) and even offered me ride to bus station. It made me think of my grandmother, and I felt homey.
The location was just perfect, as I said beach is in 3 min, if you find a good spot, water is clear and you can see many fish there. In 2 min near Chiesa Madre, there is wonderful restaurant which I visited twice. If you just walk around to main street, there is very delicious gelato place called vernaci. You can also easily go to port where you can do the boat trip.
Everywhere was so close, including main street, but it is in quite place with lovely neighborhood. I greeted everyday neighboring lady and always astounded when I see the bridge before I come back to home. Flat itself is very nicely decorated and has nice wooden door balcony. Few days in Castellammare was dreamy to me, and I will definitely sleep here again if I come back to Castellammare.
