I had a very nice stay at Hostal TIJCAL . Made reservations over the Internet, and other arrangements by email. Antonio was very helpful answering many of my questions ahead of time (in english) My room was comfortable, and I could see Plaza Mayor from my little balcony. The front door of the hostal is about 10 steps away from Plaza Mayor, very convenient location. 14 euros for Aerocity from airport. Staff was very friendly: patient with my poor spanish, helped me map out a walking tour of the areas I wanted to see, checked on guided tour schedules for me, just to name a few.
