My 8-year old daughter really loved this experience! Ioanna did not really introduce the activity but was very kind and guided us the entire time.
While a fun and connecting class, to me it was overpriced. We had some sensational art classes during our stay in Athens (silver jewelry making, Greek Dancing, and graffiti), and this workshop does not benefit by the comparison.
Nevertheless, it is a very nice activity, and I would recommend it, if you are into the "paint and sip" type of classes.
