Danial's house is at a perfect location in the centro storico di Ostuni. The terrace is definitely a hit with a perfect view and gives a great sensation of being both isolated at your own place and in the middle of this living touristic area.
When you step outside you're in the middle of the restaurants and café, and you can order a pizza at less than one meter from your door !
But even though it's living, it's mostly places where people chill and it's not too noisy.
Centro storico is car free, which is great, also you don't especially need a car to reach the place, there are bus (0,90€ but cryptic timetable) or cab (15€) from the Ostuni station (3 km) and the room is at a walking distance from the bus stop (but uphill). If you have a car, there is a public parking not far (5 min walk).
Long story short, great place and great area that I would definitely recommend.
