We enjoyed our stay in Castellaneta Marina. The house is well-equipped, there is everything we need and even more. In each room there is a ceiling fan and air conditioning, mosquito nets on the windows. Outside there is a large table for 10 people, which is all day in the shadow. Also a lot of wicker furniture and two 3-person swings.
Among the shortcomings, I can note a room with two large windows on the second floor, which was heated a lot during the day. Also there is only one bathroom for 4 bedrooms on the second floor, but there is second bathroom on the first floor, close to fifth bedroom. Third bathroom is located in the room with a separate entrance from the terrace. So we did not have big problems with bathrooms.
The way to the sea is rather pleasant, 15 minutes walking in trees shadow. Nearby there are supermarkets, bakeries, ice cream shops, pizzerias and restaurants.
Not far from the Castellaneta Marina there is a very interesting old town Matera and beautiful canyon in Laterza with a tourist trail (Gravina di Laterza). I highly recommend to visit these places.
