Roberto's place is very nicely furnished. The location was also fantastic, you could feel the Italian atmosphere.
if you are thinking about where to stay when visiting Matera and Altamura, Gravina is a great place, easily accessible. parking is not easy, though, you have to park the car about 5-10 minutes away.
The furniture is very athentic and beds are comfortable. it is ok for 4-5 people, there are 3 double beds, two of them are sofa beds which you need to open.
The bathroom is on the floor below the living area, but it has a comfortable shower.
All things considered, we really liked the place and Gravina too. I definitely recommend the place, better than staying in Altamura or Matera.
