Facundo and his management team were really responsive and the check-in could not have been easier.
The apartment is clean, the bed quite comfortable, and the radiated heat is tremendous. (If you have spent the night in an unheated house or apartment in Portugal during the Winter you will know what I mean!) The place gets lots of light when the sun is shining (with easy-to-operate shutters if there is too much glare), and I loved the enclosed and outdoor patios.
The location is perfect is you have an appointment at SEF, a couple of blocks away, or if you are in town to see a performance at the Casa da Música, just across the roundabout (Praça de Mouzinho de Albuquerque). The park in the middle of the praça is a lovely space. The neighborhood is business-oriented and has few restaurants (I can highly recommend Morabeza Boavista around the corner), but the Metro is only two blocks away and buses pass frequently, so the center and Matosinhos are not too far.
