Great Stay is what it says it is. Centrally located close to Rossio, Baixa-Chiado, and bus lines. Modern clean, and safe. Many of the places I wanted to visit were walkable from Great Stay and the rest were within an easy trip by public transportation.
Communication was clear from the beginning, the location was given right away, and check in was easy and quick.
The bed was comfortable, the window blocked out nearly all of the street noise, curtains kept the room dark, and a fan was provided to circulate air.
One note, this room is right next to the Airbnb door so you will hear some noise as people come and go. Not a problem. I slept easily.
I would definitely stay again next time I’m in Lisbon.
