Shannon hase a really nice appartment. Hilight for us was the breakfast in the garden and the rain shower.
The center of the city can be reached within about 20 minutes, best by bus. But also the corner, where the appartment is locatet hase lovely spots and a superb restaurant right around the corner.
The airplanes really are loud. But you probably wont find a spot in Lisboa, where you can't hear them. Noice cancelling ear plugs solve the problem.
Shannon really is a great host. Left a clean stilish appartment and did a great communication (online). Always there for questions.
I reccomend a stay here.
