Designs to check out in Cuba

My wife and I are going to Cuba Feb 21 - Mar 6. We are going to observe and document designs and interesting features.  
I have my PDC and my wife is a university lecturer on fine arts.
We hope to compile a list of places to check out and stay in Cuba starting near Havana.
Any ideas or suggestions welcome here.
Thanks for your time.

Howdy Mike, welcome to Permies!
I am gonna bump this back to the top and add your request to another forum to make sure it gets seen.

I hope you can come back after your trip and tell us about it !
