Joana is an exceptionally sweet & helpful young woman with an amazing loft! My partner & I were mostly without steady/reliable internet during our travels in Europe (...so it goes, sometimes :) ) & that did cause some challenges to have a clear & easy conversation regarding the necessary details. Even still, Joana was able to host us successfully; she was patient, adept & willing to go out of her way to help us.
When we re-visit Porto we'll definitely stay at her place again. It was exceptionally clean(!) & beautiful (but, so cute, too) & in the heart of the old city. Two of the amenities were noteworthy: sound/light barrier in the bedroom & recycling bins. The loft is simply great. For those who drive in there's a parking garage less than a 1 minute walk from the front door.
We totally recommend Joana's loft.
