Lourenco was great. He made sure to greet us and very thoroughly explain the workings of his apartment. All of this with great patience even though we arrived somewhat later than expected. My wife and I found the central part of the city, the Baixa, to be easily accessed by foot from the apartment. Other districts were easy to get to by a combination of walking and trolley. Lourenco followed up his initial introduction with several phone calls to make sure that everything was going well. My overall impression is that Lourenco cares about his visitors and wants to help them have a great time in Portugal.
