Great apartment. Nice view over the river. Clean, well-equipped, comfortable bed and has walk-in shower - that does it for me.
Location is convenient to walk to the historic centre and other sites of interest.
Plenty of decent eating places locally - including Michelin starred Euskaldana Studio only a 12 minute walk away!
Be sure to try Paulo’s recommendation of Casa Guedes Tradicional, just a few minutes walk away. I recommend the roast pork and sheep cheese sandwich.
Paulo was super-friendly and responsive - I’d definitely recommend this place as your base for a stay in Porto.
