We book Iris apartment as base to visit Matera and Alberobello. It was the best decision! We arrived at the afternoon and Iris was there waiting us. She show us the house and she explained everything with all details. She gave us a lot of information about where to find supermarket and where to eat in Gravina city. The house was beautiful as it is in photos and it was very clean. We found it warm as the weather outside was quite cold. It has a pellet stove which we found every evening after our long hours trips foul of pellet and burning. The house is located on the top of a hill, not far from the center but it is very quite with beautiful view and it has a very nice and big yard with trees, grass and even a playground for the kids. Iris also offered our kids bicycles to play. The yard is also secure and you can park your car inside without warring about it. In the house you can find everything from kitchen items, wifi, tv, sound system and even books and staff for the kids.
I would recommend Iris house if you want to visit Matera as it is only 25 minutes away and also Gravina is nice town and you can find anything you want. Iris is a very pleasant and lovely person and she will do the best to have a very nice time there.
