Wow. Antonio and Martinho truly went above and beyond! My flight got in in the morning before the previous guests were out of the AirBnB apartment and they let me shower and leave my bags at their personal apartment - truly unexpected and meant I could enjoy almost a full extra day in Lisbon rather than finding a place I could hunker down with my bags!
As for the apartment itself, it is very stylish, clean, and conveniently located - a 15 minute walk from Rossio Sqare and another 5 minutes to Barrio Alto or the main "Commercial Square. When I did check in they spent a good deal of time making sure I knew their favorite spots in the city and where I should make sure to go! I really can't imagine a better stay!
