Mercedes' place is a beautiful, charming penthouse, with a large balcony overlooking the plaza. Location is perfect, plus she greets her guests with delicious, fresh sangria. She has a cuddly Labrador as well. She sends you off with a portable 300mb wifi piece, and there is an additional wifi (unlimited) at the apartment. The shower is stocked, and she left out a lovely array of breakfast snacks.
I would certainly stay here again.
