We stayed 2 nights at Locanda Zacco on a 6-days trip to Tuscany. The hotel is well up in the mountains, and is a nice place with good rooms and an ok restaurant. The staff is really kind, and the male waiter spoke English very well, and was very informative on excursions, etc. The rooms are good and comfortable, and everything appeared nice and clean.
The breakfast wasn't anything special, but edible, but the coffee at breakfast was really bad. Ready-mixed Nescafé in a pot. Too bad. Their monster of a coffee maker was apparently only used when the restaurant was open. Then there was no problem with it.
There's opportunity for hikes in the area, and there are several exciting towns nearby. But be prepared on drives in the mountains and narrow roads. The roads are in good condition however. But watch out for the cyclists. The ride around in teams up here. And they ride fast , and can be difficult to spot at a distance.
