My only recommendation to the staff is that providing a home cooked sweet, instead of everything from packets, would make for an even nicer breakfast, or even something bought from the patisserie just around the corner.
An easy walk from the station, and very close to the old town, where you can spend the morning getting lost amongst the tiny winding alleys, admiring the gorgeous buildings, find somewhere for lunch, and not be too far to come home for a big siesta. And do it all again before dinner! I lived Matera and I loved this bnb. The staff were very attentive.
Thank you for a wonderful relaxing time. If I'm ever in Matera again I'll definitely be back.
