Lisa was able to accommodate our last minute request for a Rio tour during Carnival, which was the first miracle. When the guide who she scheduled to take us failed to show up in the morning, she came to our lodgings and proposed that she return in the afternoon after her morning tour and take us, herself, on an abbreviated tour. This was miracle #2 and way beyond the call of duty. We were so grateful for her dedication. Following her sage advice, we visited 'SugarLoaf' on our own first thing in the morning, thus avoiding the incredible crowds that build up during the day during Carnivale. Promptly at 2pm, Lisa arrived to pick us up and brilliantly revised our tour to reflect our interests. Somehow she and the driver managed to bring us up Corcovado Mountain to Christ the Redeemer, through the city for an enlightening stroll in the fabulous Botanic Gardens, and finally on an eye-opening walking tour of a favella. She shared so much information about Rio, its neighborhoods,buildings, beaches, people; we felt like we had spent a week not an afternoon with Lisa. She was truly knowledgeable about her city and also a friendly and fun person to spend time with. I cannot recommend her highly enough.
