Lucia is an absolute star. She is very kind and caring, and she's always available to help (she lives just above the apartment). She offered us coffee every time she came home and was very quick to come down when we needed her. If we lived in Martina Franca we would try and become best mates with her. :)
The apartment is about a 20 minute walk from the centre of the old town, and you have to walk through a safe but not pretty area of ugly apartment buildings to get there. If you are only going to drive everywhere this doesn't matter, but if you are wanting to be able to walk into town this probably isn't the apartment for you.
