Nothing to dislike.
Graffiti B&B is boutique chic in historic Matera - it's great place to stay.
We stayed only 2 nights unfortunately, as we would have loved to have stayed at least another night. The rooms have a lovely modern decor, and are spacious and spotless. The walk-in wardrobe/dressing room is a real bonus. Bed and pillows are very comfortable ( we'd had a long drive to reach Matera), and we slept well. I loved the crisp white towels, and the excellent water pressure in the shower. We had free wifi in our room, and enjoyed a spectacular view of the ravine and the river from our window.
Nicolo' is an excellent host, giving expert advice for seeing the sights, and for eating out well at a good price. He provides a delicious breakfast - his mother's cake is to die for!
We found Graffiti easily from the south, and used the free roadside parking close to the B&B.
The location of Graffiti B&B is perfect, we never used the car, but went everywhere on foot.
I would definitely stay at Graffiti B&B again.
