Really nice, stylish apartment in the center of Lisbon. Location wise it's hard to get anything better.
Windows overlook one of the squares, but they're properly isolated against sound from a street, so once windows are closed, it's really quiet inside (and air conditioning is everywhere, so if you need to vent an area with closed windows, it shouldn't be a problem)
All was great for us for the weekend stay, I just wished that the double bed was a bit bigger :)
