You should just stay here when you visit Lisbon! I've been traveling for months, staying mostly in Airbnbs, in Europe and this is one of the best places I've stayed at! Great value for the money and you're on a tourist attraction street (though it's not noisy because of this actually). Place is clean, nice, spacious, and has a nice feel to it. Only thing worth pointing out is the stairs, but they really aren't very hard to walk up at all.
