Definitely a flat on our recommendations list fir anyone visiting Ostuni.
We were welcomed very warmly on arrival. It was easy to contact the host on the phone. There is nearby off street parking. Great location of the flat off main square. Things are quiet.
The flat is over two levels with access through staircase off the street (loads of steps ;) but worth it). The flat was immaculate and bright. Nicely decorated. All we all three needed was there, even a high chair for our two years old.
We went in November (heating works just fine in the fkat for cooler nights) and Ostuni was at its best and almost without any tourist. I really recommend Ostuni and this perfect accommodation.
