Apartment is located in a convenient spot for visiting the city and it is in a safe area. There is metro construction going on bit lower the street, but as apartment is facing the other side of the building - there was no noise neither from street or construction. Elevator in building was very convenient.
It was very easy and simple to check-in/out.
The view outside overlooking the roofs & Clerigos tower is nice as well. We enjoyed sitting outside on balcony, especially in the evenings.
Apartment was clean & interior looked like refurbished recently.
There is a great breakfast/brunch place just downstairs, though it is better to get there closer to opening time as it gets busy.
We would definitely stay in this apartment again, when visiting Porto!
