I stayed 3 nights at Antonio’s and Antonella’s place as a single traveller.
First the positives .... all the comments about the hospitality of A&A are true. They really are nice people. The place itself is in a modern building and the bedroom is more stylish than most upper end hotel rooms in which I’ve stayed. It’s a lot more than most people expect of an Airbnb room.
For me though, the biggest downside was that the place was further away from the train station than I had thought and there is no public transport to / from the station. I had intended to use Polignano as a base to make day trips to nearby towns so proximity to the train station was important to me. In the end the distance didn’t matter so much as Antonio offered to pick me up from the train station and drop me off there on my departure day. He also drove me to one of the nearby towns I wanted to visit. The train station is probably about 1.3 - 1.5 km - in itself not really a huge distance it’s just that I had thought it was much closer. I can’t comment how far the place is from the beaches as I didn’t visit them.
For me the other downside is that there is no use of the kitchen to prepare tea or coffee as you might want or to prepare simple meals. Again, it wasn’t much of a problem in a 3 night stay and I think this is mentioned in the listing. Breakfast is offered - which may or may not be important to you - but it does bring with it the necessity to advise the evening before at what time you want breakfast and different people have different ideas if what they want for breakfast. A&A accommodated my request one day to have scrambled (there is only so much pizza, pasta, panini and pucce one can eat after 3 weeks in Italy).
