Good location, check in/out was easy! I would recommend this host.
Couple of very minor things need seeing to - raised in private review. There is a smell coming from Kitchen/Bathroom, like cat food. However, there is some massive very deep road construction outside which I assume is sewer related (you can't hear or see it from the apartment).
Otherwise generally looks like the photos and location/description is accurate.
I would stay again, but my next trip to Porto I will probably wait for all the major roadworks to be finished as the city is quite a mess right now. Once that's finished, the location of this apartment will be even better.
