In reply to Carpe Diem:
We have three apartments at the foot of Passo Fedaia in the Dolomites, which are just right for what you are looking for. We are surrounded by some of the finest climbs in Europe with the Giro d'Italia passing us twice during the hardest mountain stage. There's Passo Giau, Passo Staulanza, Passo Duran, Passo Falzarego, the Sellaronda - just too many to mention. For example, the most famous ride is this one:

There is also the Maratona dles Dolomitis which is a world famous event with various lengths to suit your pain threshold.
The GCN channels also have loads of video of the riding around Alta Badia.
