The flat is on the fourth floor of a house located on a quiet street in the neighbourhood of the tourist areas.
When I checked in, the flat was missing soap, salt and a couple of other little things (apparently I was the first tenant in the flat), but when I wrote to the landlord about it, he promptly restocked it all. The kitchen has all the necessary utensils. Air conditioning units heat the air well during the colder months. The window has a great view of Porto. There is a supermarket, coffee shops, restaurants and a metro station within a five-minute walk.
Highly recommended.
