I stayed at Clodia's apartment early July with my boyfriend and we had a lovely time. Her place was perfectly located right in the centre of the old town. She welcomed us with a smile and showed us around the flat. The place was bigger than it looked on the pictures. The bed was really comfortable, Everything was very clean and it had everything you would have needed for a week stay.
The town seems to always have events on in in the summer which is great as the streets, restaurants and bars are really lively, we were out every evenings trying different restaurants and bars. We were there during the very popular literature festival so the town got really busy in the evenings. This meant it did get quite loud outside the flat at times but never too late and once you 'd close the windows you couldn't hear much so actually it didn't bother us.
We loved Polignano and would happily stay at Clodia's again!
