Our stay in Lisboa was great ! Choosing this flat happened to be a very good decision. Gonçalo is the perfect host. He was always available for helping out and this was very appreciable.
The flat is in a very living neighborhood, especially at night, with many bars and restaurants. We were therefore a bit afraid of having to much noise. But we didn't. The double window was very efficient and we slept like babies :)
You should definitely contact Gonçalo for your stay in Lisboa !
