Irina and Ricardo are fantastic hosts! They provided directions on how to meet them and provided great suggestions on site seeing in Lisbon. They also helped me get a taxi to the airport when my flight departed very early in the morning. They were also very responsive to messages.
The apartment is very spacious, clean, and ideally situated. Within ten minutes walking you are in plaza de comercio or Santa Apolina train station. The apartment is in Alfama which provides a lot of great restaurants and charm. The only downside of the apartment is that it can be quite loud at night. I stayed over two weekends and music played into the middle of the night. Otherwise, highly recommended!!
