Well, what can I say. Awesome hosts, awesome flat. Nothing less, if you're looking for a cool flat in a cool part of town then this is the one. It has an amazing terrace which is basically unheard of in the area and the flat sits on one of the best squares in Lisbon. Carlos and his partner are always there if you need and they even brought me berries and spinach from their farm - who else does that!
It's a no brainer, I have stayed in many airbnbs but this was by far the best.
