You can book tours directly on their website; which I advise you to do (link: https://www-14e.bookeo.com/bookeo/b_2144H64UT13FCAA886B6_start.html) I just checked, and they do tours in the 21st
Book a tour through the website. When we went it was about 15 to 20 people. The site does not give particular days. I think they base then on if there is a group. It was fun and delicious. Your in for a treat.
