Free walking tour Centro storico di Guadalajara essenziale

It's strange how they advertise it as Sergios tour when the guru isn't Sergio. Our guru Mari was very knowledgeable and kept the tour fun. The one upsetting part was when booking the tour we were told the guru would be waiting for us at the meeting spot at 11am. We arrived just before and they had already left, so we went into the hostel and asked the staff to help us find the tour group. Discovering the tour was advertised on their wall for 1045am so it makes sense why they had already left. Luckily we were able to track them down searching around the first couple tour spots. The communication with Sergio through the Guruwalk website was unsuccessful.
