Great little apartment, totally as described. Brilliant location next to the river and within walking distance of all the main sites in Porto.
We had a great stay and would highly recommend.
The only thing to be aware of is the door to the bathroom is made of glass, doesn't close fully and is right next to the bed, if you're travelling with someone who you're not ready to share all of your bathroom time with then you might find yourself having to take turns to sit in the kitchen area!
