Excellent stay!
Appartment was new, super clean and with all you can need. There is a lift and building is clean.
Location was in center and close to many points of interest (5 to 10min walks), a big choice of restaurants just around the corner, and 4min walk to Trindade station.
Instructions for check in were very clear and practical.
We enjoyed it a lot and would definitely go back to the same place if we come to Porto.
