This is a very convenient location if you want to see Porto. The major sights are literally a walk across the St Luis Bridge. The metro D-line stop is a 2 min walk. The bed was large (a king size) and comfortable. Shower water pressure was great and hot ! The wifi was fast, no issue being on a video conference call.
There are grocery stores (Pingo Doce, Continente, Lidl, El Cortes Ingles) and cafes right on the main street. The kitchen has the essentials if you are inclined to cook.
The bus to the beach is also around the corner. Great communication
It can get a little loud with the train and external noise if the screen door or window is open otherwise it is quiet (trains don't start till 06:00)
