Francesco is a very nice and friendly host.
But I feel like the reviews are misguiding about the apartment,
It is very small and the feeling of privacy is very limited. The bedroom and living room are separated by a door which is mostly glass. And the bedroom is separated from the kitchen by only a curtain.
As we stayed on 2 nights it was ok. But for longer than that it would be difficult.
Also in January it was freezing in the house. There is no central heating. Only a very very a weak electrical heater...
there is some kind of electrical bedding to heat the bed.
But we spent most of our time outside at restaurants as these were warmer.
Polignano is a turisty little town but there is no point visiting in the winter. Spring and summer is the time to visit. Everywhere in the old town was closed.
Anyway, if you are ok with the cold and lack of privacy it may be suitable as the apartment is very clean and Franceso is a very nice person. Eventough he doesn’t speak any English he was helpful and cheerful.
