The city is simply stunning at night and Natalia, our guide, ensured we saw the best of it. She was extremely knowledgeable, as well as being excellent company, and I don't think we could have learnt as much, or seen as much in a short time, any other way. As well as taking us to the main attractions, and giving us time there to explore on our own, Natalie kept up a continuous commentary as we drove around, pointing out so many features we would otherwise have missed. The electric cart was comfortable and afforded us great views. An unexpected cloudburst at the end of our trip led Natalia to offer to take us directly back to our hotel so we wouldn't get soaked waiting for a taxi. Beyond the call of duty and much appreciated. We highly recommend this tour.
