Old havana has so much history and beauty and we've just returned from 8days there. We would never have been able to fully appreciate it all, were it not for a guided walking tour on our 1st day, which orientated us to the sights (there are many) and gave excellent recommendations for what would bring our holiday to life.
We found our guide Cary through Jorge (email@example.com). Good rates and her enthusiasm and wealth of knowledge were well worth it. Only found out Jorge and his fellow guides on this forum (thanks to others for posting their details) and I highly recommend them to anyone thinking about spending any time in havana. Enjoy!
