Paulo is probably the best host I've had on AirBNB. He is incredibly responsive, and he has an extremely thorough guide to the city. I came to the city not really knowing what to expect or what to do, but I followed his guide and I had such a incredibly day. Paulo met me at the door of my lodging and gave me a tour of the place and pointed out all the amenities to me. I don't think I've ever had so much personalized attention from a host.
Paulo's also just a really great guy to get to know and talk to. If I could give him more than 5 stars, I wouldn't hesitate to do so!
