There is a beautiful view from the apartment (because of the vantage height), and Marisa's apartment has everything you might need -- from kettle to oven to breakfast that she thoughtfully provided. It is a good size for about three to four adult travellers - with two toilets, kitchenette, balcony and a living room that can be partitioned, and an elevator to the apartment if you have elderly family.
Porto is hilly, and there is an uphill walk to Marisa's apartment, so be aware if you have a lot of suitcases or your party is less mobile. You might find it easier to get a cab if you do. Fortunately we found a shortcut over the next few days!
