I can't recommend this place highly-enough. The views are to do for, and we received envious glances from the square's cafe patrons as we unlocked the door to the apartment stairs. Be warned, there are a lot of them, so not ideal if you are not up to the climb! But boy, is it worth it if you can. Quite apart from the location over the beautiful and centrally located square, Mercedes is a brilliant host who strikes the perfect balance between warm hospitality (even homemade sangria when we got home every afternoon/evening) and privacy. And the friendliest dog ever.
