Wonderfully large and airy duplex with all the amenities needed for a long or short Porto-stay. Close to shops, good restaurants and grocery store. Also great hosts who went above and beyond to ensure our comfort, and even let us in early with the luggage. Super quiet and calm, but very close to everything you need.
A few minor things like the downstairs felt a bit chilly and damp, but Porto seems like a very humid city - so it's probably like this everywhere. Also the next-door house seems to be undergoing some renovations, which woke us up one morning. But didn't have any disturbances the rest of the stay.
