In reply to Dan Jam:
We were in Sardinia over Easter, there are lots of climbing opportunities of all kind.
I can't help with accommodations because I was there with my family and we had only small house rented.
For climbing we tried the canyon in Ulassai, which as described is a large area with 150 routes in nice Dolomite, closely bolted. Because of the canyon nature I think it is quite shady in the summer. Tehre are some climber specific B&Bs in the town of Ulassai but not much else.
We also climbed near Baunei at the cost, in granite. This was at the Pedro Longa area, there are several crags directly next to the street and multi-pitch climbing is possible at the Pedro Longa itself in a stunning environment.
For guides we used the "climbing maps" of Ogliastra which has a map on the one side and the topos n the other. We also used the 2018 released Jerzu guide for all the crags in Ulassai, Jerzu and surrounding area. For the coastal area we climbed there would also be a just released Baunei climbing guide, which is useful if you want to do the multipitches. It was available in a local shop in Santa Maria Navarese.
For Cala Gonone there exist several guides including one at the vertical Life app. I didn't use any of them though.

As a general advise consider that all driving except on the major highways takesd place on windy mountain roads. The roads are usually in very good condition just steep, narrow and lots of curves. Average speed maybe 50 kph, so don't plan on driving long distances.
