I stayed at this wonderful apartment for three weeks. On a one to ten scale, I would give it a 15. The apartment's decor is warm and comfortable throughout. The floor to ceiling windows provide tons of light. The beds are super comfy and even the showers are great -- excellent water pressure.
The location of the apartment is also outstanding. It's in a vibrant and fun neighborhood, with the famous Pink Street, Time Out Market, and Cais de Sodre train station just a few minutes walk away. There are also several excellent cafes a short walk away and a great little coffee shop right downstairs. In addition, the funicular to Bairro Alto and Chaido is about twenty paces from the the front door, as are the stairs for those who like to walk.
Finally, a word about Constança, the host -- I've stayed in many AirBnBs around the world and have never had a more pleasant or responsive host. She is just terrific.
In sum, I would be hard pressed to think of a single thing I would change about my stay. The apartment is great, the location is excellent, and the host is wonderful. What more could a traveler ask for?
