The place is amazing, just as described. Fernando is responsive. If you arrive to Porto early, they have an offsite Welcome Center where you can store your luggage until check-in time.
The only thing I would make future guests aware of is that this unit (H) is on the top floor (3) and the building does have an elevator/lift. If you have heavy luggage, you might want to practice leg day at the gym before arriving. You might also want to ask to switch to a lower floor unit like B (on the bottom floor) or C & D on the first floor.
Other than this, the place is great. We didn’t make use of the little sitting room on the second story of this unit but it’s really a great additional space.
