I attended a guided tour first thing on a Tuesday morning and there were only 4 of us in the group. Our tour guide, Patricia was amazing. She really went in depth with the details and history of the house. It is only a few euros more to do the guided tour versus the audio guide and I would highly recommend the guided tour. Make sure to explore the local Gracia area as well - there are many boutique shops and cute cafes within walking distance of the casa.

Beautiful building embodying Gaudi's amazing designs. Casa Vicens was the first building that Gaudi designed in his life, and frankly it is a perfect depiction of his brilliant mind. The colours and architecture are all unique and Gaudi created illusions in such a way that a person seated inside the building would feel they are sitting outside under the clear sky.
