I would say this is quite a basic apartment, but for the price and the location it was worth it for us. There are a lot of stairs to climb, so bare that in mind when booking, the view from the living room window is stunning however. Also the kitchen and bathroom have quite low slanted ceilings, so not ideal for anyone 6 foot or over. Some work could be done to fix some issues with the shower.
But all in all it's a nice place to stay, if you are planning on spending most of your time out exploring Porto and don't mind staying in a very basic apartment, then this is for you.
