I had a wonderful time at Maso Bergamini! The room is very comfortable, the surroundings are beautiful and Damiano is an excellent host who helped me understand what to do in many situations. I only speak a tiny bit of Italian, just enough to go to a restaurant or buy something in a bakery, but communication in English was very easy. The breakfast is typically Italian, sizable and tasty. I also would recommend you to make use of the fact that you are staying at a vineyard, buy a few bottles or book a tasting! I really can not stress enough of excellent the whole experience was!
If you arrive by train, I would suggest to first buy a ticket for the local bus you will later take to the Maso. It is 1,20EUR (there is just one type of ticket apparently) and you will stamp it when entering the bus to make it valid. You can buy it in the station and check the time table for the Bus to Villamontagna (your stop is Tavernaro Central) right outside the train station. Then turn right to leave your luggage at the nearby intercity bus station (stazione delle autocorriere) where they have lockers for rent. When you are good to go, visit the tourist information just on the other side of the park and ask for recommendations, walk around and later return to the train station to get your luggage and hop on the bus. When you get off the bus at Tavernaro Central, there is a smaller road leading from the main road that you can just walk along. I was at first puzzled by this, but these tiny roads are used by people on foot, on bicycles and cars alike - and it just works. Also, sometimes it feels like you are walking across people's yards (which you aren't and shouldn't do!), because it is just a few houses directly at the road. This goes for most roads/paths around the Maso. From there on, it should be easy enough to follow the road to your destination.
