jekaterina was a good guide. we waited for a bit outside casa vicens because there was supposed to be another couple with us but they no longer joined us. jekaterina knows a lot about gaudi's history and the secrets about the houses he designed. she speaks a bit fast and with a quiet voice so sometimes it's hard to hear her, thankfully we were just two in the group. she gave us good recommendations on where to eat (thank you, recos were very unforgettable too!) we saw battlo from the outside and she left us once we entered casa mila. overall the gaudi tour was very interesting and we learned a lot from her.
