This is a great place, João is very helpful, hospitable, he gave us lots of useful tips on dining out, nearest supermarkets, top sightseeings; and Porto.. it is magical, charming, I bet it's one of the best cities to visit and explore! Apartment is just what you'd expect it to be from photos, few minutes away from Ribeira square. The windows offer amazing view on the river. Definitely one of the best places I stayed at, very much recommended!
One tip for future travelers! If you go by taxi make sure you set your destination to Porto's Cathedral (or Sé do Porto in Portuguese) and not the actual address, because drivers will drop you at embankment and you'll have to find your way through lanes and pass a LOT of stairs up :)
João pointed it out before our arrival, but still I was too careless and set the destination in Uber as Escadas do Barredo 120, hoping to explain details to driver. Unlucky enough, the driver did not speak English well and drove us exactly where his GPS navigated him, which was at embankment :D
Kudos to João as he offered to pick us up down there, but we found help from some kind hearted locals, they shown us the way and even helped to carry the bags, while João also hurried down the stairs to help us :) now that's what I call outstanding hospitality! And that's all about Porto - kind and friendly people just add up to the romance of this city, making the trip unforgettable and leaving you with a desire to come back here again!
