First of all, if you are driving, this is not located in the town on San Vero Mills, but in the town of Putzu Idu. It can be confusing as SVM is a town and an area.
Once we stayed here a few days I wished we had not chosen this spot. There are such better towns and beaches just north with much more to do and much prettier towns and beaches. I really see little reason to visit this town.
How this hotel has 4*, I don't know. It is fine and clean; it is just a very simple 2-3* hotel. No real services, poor sheets and pillows, rubber curtains, individual dispenser for bath tissue, etc. (They even suggest to you that the individual bath products are not for "one use" - I guess they took care of that problem as they installed the wall dispensers.)
The grounds going down to the "beach" are nice, but, in the land of gorgeous beaches, this is not one of them. It is a rock beach - not the little rocks you can walk and sit on, but rocks of several inches in diameter. And, there are two private houses right there. Not a beach you are going to spend the day on!
The people at the restaurant were very helpful and friendly and breakfast was nice. The dinners offer just a few choices in a brightly lit room - very strange setting. (Wine but no liquor service.) It was just OK. We didn't want to return more than once.
