Lovely apartment. Super clean, wonderful hosts, and perfectly located. Elevator, grocery store and Alfama right at doorstep. Sweet wine tasting shop across the street. Wonderful to watch city come alive from balcony. And when it was time to unwind, close doors and city sounds blocked. This made it perfect for sleeping.
I prefer to have fresh air so bought a small fan at grocery store and left it at apartment for others to use, if hosts leave it there.
Definitely recommend booking this stay in Lisbon.
