If you go, go on sunday.. Sunday's are the best!
Also, hostal Nomades is the awesome and they know how much you should pay for souvenirs.. and where you can get the best hammocks or hats for the best price..
If you want a free tour around the city, you should look very-tourist-like and wander around on the mainsquare.. If you're lucky there will be a guy who tells you he really wants to learn english and give you a little tour, you should ask questions and let him show you everything and tell all the stories, they know their history... Actually it's just a guy who tries to convince you to buy something, locally made.. but before they get a chance to fool you, you fooled them ; )
