A flat in a very central location of Porto. 15 min walk to even the furthest of the main sights, and a delicious market is right around the corner. The reasons for a 4-star rating: (1) No cancelation policy. (2) Lights in the staircase [still - I am not the first client to complain] do not work. (3) No heating (only AC with heating ability). (4) Water in the bathroom sinks drain very slowly. As for the sink, they immediately improved it a bit when we arrived, so that is a plus. Overall, if you don’t mind those downsides, the place is otherwise great and quite recommendable.
