We stayed in the suite for one night. It was spacious and nice. Unfortunately it was not as authentic as maybe some of the other rooms are - i.e carved out. It was an experience all the same.

Pros: The view accross the balcony were great -into the old town. The breakfast was nice - as expected for Italy. The staff were very helpful. They booked for us an English speaking private tour of the sassi - with a guide who was brilliant.

Cons: The 'double bed' was as typical in Italy - 2 singles beds together - this is normally fine however the two beds were slightly differnet heights which was annoying.
The hotel is a nightmare to find. Based on previous reviews, we had maps printed and walking directions from the parking garage and we still got lost!!! Once found though we were only a 5-8 minute walk back to the main square with a few steps but not a ' steep 40 meter high climb' as stated in a previous review . I do feel the hotel should print out directions (or email them to you on booking) using not just road names but possibly landmarks - possibly from the main square. It would make for a more enjoyable stay. That said, we got there eventually and anyone we asked pointed us in the right direction.

I have nothing more to add to other reviewers but only confirm what has been said already. Our room (in a cave of course!) was spacious and comfortable. Our balcony had a stunning view overlooking the caves of Matera.
Despite some negative reviews regarding humidity and cave dust in the rooms , we were lucky and did not experience any similar issue (perhaps because we were in June?).
I can also confirm that the Breakfast Buffet was delicious (try the “pizza bianca ” with sugar on top ...it’s something special!) . The Staff is really friendly .
Only few advices : avoid heavy luggages/trolleys due to the steep steps leading to this hotel; wear confortable shoes due to the alleys paved with cobblestones and ,when possible, avoid the car since parking are a bit far from the caves area. From Bari Airpoirt (70km ) there is a shuttle bus service to Matera for only 3 euro (one way) You can book on-line at following web site: http://pugliairbus.aeroportidipuglia.it/ .

We arrived in Matera in the rain, having previously booked two nights at the Sassi Hotel. After a long and frustrating search to locate it (a distinct lack of signs) we discovered that we faced a steep climb of about 40 metres high, via treacherously dangerous exposed cobblestone stairs, down which a torrent of water was pouring. I went on ahead to scout the way and eventually arrived at the hotel, completely soaked, having nearly sprained my ankle of the slippery steps. I was shown to a room that was dingy and depressing and furnished like a college dorm.
I was informed that there was no-one to help us with our suitcases - we would have to struggle with them ourselves in the rain to drag them up the cobblestone steps ourselves. This would have been virtually impossible so, with the image of the sad, bare room also in my mind, we went elsewhere. Not only did they keep our deposit, but we were also later charged the full cost for the two nights. An entirely crappy episode.
Do not stay here - even if you make it to the hotel without killing or maiming yourself, you will be sorely disappointed by the threadbare, dingy rooms.

This hotel is difficult to get to because of the city's steep hills, but it is well worth the walk. As suggested by its name it is located in the historic Sassi district. The staff is helpful and friendly and the breakfasts and views are special. Stay there is you are in the area.
