very agreeable free walking tour. Taty is good company, a calm and natural and sympathetic person and seems to know a lot about the city. She offers tours in Spanish and English and her English was good and easy to understand though she doesn't talk very loud and sometimes I had to make an effort in order to hear her clearly through the traffic noise. Anyway, it's been 2 well-spent hours and I can recommend it

She was very friendly, and made jokes all the time, she was also very natural. I liked that i vould ask any question and she explained , without get pissed off ( i had this experience already) she knew a lot about everything and spoke a good english.. 

Taty was an excellent guide with good English, explaining in great detail the history of each place she showed us. I enjoyed her tour very much!

Very informative tour.  Guide was also kind, easy to understand, and enjoyable to be with.
