Regardless of the heat, Lexi was a cheerful enthusiastic guide of Cartagena. All the food was authentic and purchased from street carts. Was a highlight of our week in Colombia and is highly recommended. We wandered through the walled city and a bit of Getsehmeni neighborhood...which we had not been to previously. Only disappointment was starting the tour in a chocolate factory and not getting a taste...otherwise, reserve you place and request Lexi!!
