I can highly recommend staying at this place while visiting Porto. We especially appreciated the check-in process, when we were warmly welcomed and well-informed on the places to see in the neighbourhood. Even though the apartment is rather small, it is comfortable (the pull-down bed works well), clean and tidy, fully equipped with the most important appliances (including AC), and very bright thanks to amazing window panes. The place is nicely located in, with small walking distances to reach all the most important destinations. After you check out, you can still store your luggage there before you leave the city.
