Martin's place was the coolest decorated airbnb I've stayed at.
he's very friendly, got us some welcoming gifts, classic Portuguese pastries and a bottle of wine.
the location is great, right in the middle of biaxa, walking distance to most everything a tourist will want to see.
Couldn't be happier with this place.
One tip, bring comfy walking shoes! Lisbon has lots of hills and is all cobble stone.
