Best Airbnb we have ever been to. Felt really fully 100% welcome and comfortable for the first time - after many other hosts and rooms world-wide.
Note: Steep hill-climbing is required to reach the place, beware if you have reduced mobility. It's a typical Lisbon issue (or "feature") though – there is no Lisbon without its 7 hills (unfortunately :D).
We loved it, and we'd absolutely come back to Antonio's place.
