Booked this experience last minute and I enjoyed taking part! The host was good at communicating with me prior to attending and answered any questions I had. Great price for the amount of time you have to paint two tiles! I think the start of the workshop seemed a bit abrupt but once we got into it, I learn lots. If you choose to free style your second tile, try to prepare some ideas before hand so you can spend more time on painting and less time on thinking of what to draw. Also try to book a few days before you leave, so you have enough time to collect the tiles before leaving Lisbon.
