First of all, we had a really difficult time finding this place - it was not on the tourist maps (it's not part of the tourist ticket), and we finally found the address based on my advance research and you could see an empty room inside but no information telling you to go around the building - we honestly thought it had closed or moved somewhere else. (My sloppy-handwriting notes say it is at the corner of Ataud and Colebras.) That being said, it's a tour on your own, and the signs are not unreasonably mostly in Spanish...but with no guided tour and us not reading Spanish, it's not much of a visit. I'd say maybe 50% of the signs were in English, which is certainly more than they need to do, but we didn't get a lot out of the visit. We did enjoy the pottery. We did not see any demonstrations going on in the courtyard as others did, but perhaps it was just too late in the day.
