We had a great time in l'Antica Marina. The apartment has the vibe of an old farmhouse. It is sufficient for three people. It has a bedroom with a large 2-pers bed, and one with a small twin bed (maybe 1.20, probably less). There is also a couch but that is not suitable to sleep on. The kitchen is equiped. There are clean towels and bedding.
We liked having our own terrace at the apartment and plenty of space in the area around the swimming pool. The garden is full of olive trees and fruit trees.
The apartment is at a 10 minutes walk from restaurants and cafe's in Martina Franca. However you do have to walk on the narrow side of a road with some fast traffic.
The town is very beautiful. You'll have a great stay here.
