I highly recommend Cristina as a local friend. I scheduled a full day with Cristina that included a visit to Tijuca National Park, the Cristo monument, and the artsy neighborhood of Santa Teresa. Cristina was wonderful! She was friendly, thoughtful, organized, flexible, offered several options for things to do, and was knowledgeable about her city and its cultural activities. She makes sure to ask you what your preferences and interests are. She is easy to communicate with and she has a car, so getting around Rio is easy and comfortable. She later sent me a follow up message with suggested walking routes and other helpful tips and information. If you want an excellent local friend, book Cristina!
My wife and I enjoyed a wonderful day with Luciana. We had been on tours of BsAs from the general to specific. From Luciana we asked for more of an "organic" experience. We wanted to wander the city as though we lived in BsAs. Doing things and sharing the day like we do at home - chatting, seeing parks, visiting cafes, shopping at ferias... We planned a couple of museums too, but the weather was beautiful so we followed where the day took us. She even arranged for us to share her homemade mate.
What a great guy. He was so helpful and friendly. Nothing was too much trouble for him. I would definitely recommended Juan if you are wanting a genuine local to show you around. Made my time in Bogotá special. Thanks Juan and also to his lovely girlfriend Paula.
