Sergio checked us in quite late, which was nice. Both he and Sara were available to us for help, which, happily, we didn't need. Well located in Bairro Alto on a cobblestone street. Uber got us ere easily from the airport, once we found where to get picked up (arrivals parking).
Streets were a little noisy at night since the place is near the night life. With the windows and shutters closed most of the sound was indiscernible.
We stayed four nights, with one of those in Sintra. Google maps worked pretty much everywhere, making it easy to walk places. We also bought the three day yellow bus passes, then had fun mlking our money's worth out of them.
