We loved the apartment, it was located in a quieter bit of town but only 10 minute walk to lots of amenities.
The apartment was light, bright and airy and very peaceful. The shutters in the room made sleeping a breeze!
My only comment would be that early check in isn't an option and the luggage storage facility isn't walkable. If you have just arrived and don't know Portugal it's difficult to know where to get your taxi to if not directly to the place you are staying.
