It was very easy to contact with Martin and, even if we hadn't the pleasure of meeting him in person, his friend Laura received us, showed us the flat and gave us good hints about the neighbourhood.
Overall a great experience, the flat his very well located and is out of the common tourists neighbourhoods so is very quiet. Beautiful place to stay for a couple or 2 friends, I would definitely recommend it and will repeat if I had the chance!!!Thanks a lot!
