Roberto Indeed is a SuperHost. Weeks before my trip he sent me welcome packet via email with all the necessary information about transportation options from the airport, train and throughout the city. Also, he provided all the to-do's, and basic tourist information. Since the arrival, he was very friendly and available, but always respecting my privacy. His place is very very centric and well connected. Salamanca District is beautiful. Must try Mercado la Paz, which is 200 steps from Roberto's
Overall, will highly recommended. Felt like home.
