This was my first experience with Airbnb and I learned that it is very important to be able to communicate any delays to your host because they might otherwise not be at the apartment when you arrive. In our case we arrived 1.5 hours later due to a long wait in immigration at the Lisbon airport. There was nobody at home. When we contacted Joel, he quickly called his friend Silvia who had waited for us but had left. Silvia got back to us and offered some options which involved waiting for another hour or meeting her at some place in the city to get the keys. We decided to go to a local restaurant nearby and Silvia met us there within the hour. She was very nice, friendly and informative about the city and its points of interest. The rest of our stay was very nice. The apartment is at a great location and the other people staying there were friendly and respectful. Thank you Joel and Silvia.
