This place is perfect! We stayed a couple of nights and very glad we choose this place. It is in the center of everything! We walked to all sorts of sights and when we didn't walk it was very close to the public transportation.
The hosts were great too, we were delayed and they were still very accommodating. Gave us very useful information and left a welcoming gift.
AIR CONDITIONING!!
It is a walk up so be ready for stairs but it is Lisbon and there are stairs all over so no big deal. :)
No complaints at all, loved it and highly recommend this place to everyone!
Use Uber to get to and from airport, very cheap.
