As a group of three, we stayed in Michele's flat for one night. It is located directly in the old town of Gravina which was very good. We got the feeling how locals live here. What has to be mentioned regarding location: we highly recommend not to drive straight to the address, the streets are locally extremely narrow and there's a great risk to get stuck with the car. Apart from that, we didn't find free parking lots close to the apartment.
Michele as a host was very helpful, friendly and also invited us to his pizzaria with a 20 % discount.
The actual bedroom had was very nice - the second advertised bedroom contained a sleeping couch (leather) and a small bed which we can unfortunately not recommend sleeping in - in our opinion, for in total 5 people the flat could become uncomfortable.
We were given some sweets for breakfast.
We wish every guest a nice stay in Gravina.
