The place is very quiet. Good wifi connection. Hot water (not disappearing after 3 minutes as in many places in Italy). A working TV. Very nice hosts (welcomed us in the middle of the night and were otherwise very helpful). A medium-sized shop is a 10-15 min walk away. A great place for visiting Matera but further away if you intend to visit trulli country or Adriatic coastline (but that is obvious looking on the map, right?).
The only thing you have to keep in mind is that the living spaces on the 1st and 2nd floors are not really separated, so no real privacy. If that is not a problem, the place is just perfect.
