So of the dozen or so airbnb's that I have rented over the past 3 years, Joana & João's was by far the BEST experience I have ever had! Not that I have had a bad experience with any apts. but it was the "little things" the little touches that make this apt. & our stay so amazing.
1st the place is exactly as described & the pictures show. In fact even more cool in person to see what architectural design they've used to maximize space & light in the apt. The place & everything in it is brand new & completely re-done in a very old building.
The neighborhood and surrounding neighborhoods felt very safe to walk in, even at night and there is plenty to do. You are literally in the heart of all the action. It is not in front of you on the street, it is a fairly quite neighborhood but a five minute walk in any direction gives you anything you would be interested in seeing including down to the water.
Joana & João had put together a book of their "favorites" and things to do in the neighborhood and the City. They had amazing recommendations for restaurants, sightseeing, cafés, getting around and things that are special and that locals do on the weekends.
Additionally in the apartment they provided wonderful books about Portugal and Lisbon, maps and other special things too really get you into the culture and how the city works.
Response was almost immediate whenever I reached out to them. I cannot say enough good things about our stay in their place, certainly we would use it again and I highly recommend booking it!
