The Holiday Inn-Zocalo was a very nice experience for me in March, 2013. This hotel thought about the little things. Some examples include...1.) the "desk chair" was more like a tall ottoman but very functional as both and nice looking; 2.) the air conditioning worked!!; 3.) the Internet was adequate enough that I could make voice calls on Skype; 4.) very stylishly designed and in very good repair.
Around the restaurant are many things to see including The Cathedral which was a stone's throw away. Many eating place in easy walking distance includine coffee places.
I am returning to this hotel by choice in 2 weeks because of the great value and the relaxing stay it gives me.
