Was it easy to get a taxi to/from or did you have to pre-arrange one? Also, did you hire the English guide once you got there or is that something you set up in advance? If in advance, how did you make the arrangement?
I'm so sorry for the delay in answering your question. Somehow TripAdvisor isn't letting me know when I have a question waiting for an answer.
We had not problems finding a taxi after arriving at the train station. There was a taxi dropping someone off, and we just jumped in. After the visit to Caseificio San Pier Damiani, they called a cab for us and it took about 10-15 minutes for it to arrive.
We did not use an English guide. I believe you can let them know you want a guide and they will provide one for a fee. But we downloaded an audioguide before we went. I think they send the link to us when we made the reservation. And we listened to that while we were there. It explained everything that we were seeing. When we had questions, we used our feeble Italian or I used Google Translate to get the idea across. While it might be nice to have an English guide, I don't think it's necessary. You can figure out what they are doing by just watching.
Enjoy your visit there. It's a very nice place. We were the only ones there on the day we went but even if you had a big group, it would still be fascinating. It was a highlight for us.
