A fabulous mini-studio with incredible views in which we stayed for two weeks (Feb-early March). The room is minimalist (think very large family-sized tent) but has absolutely everything you need, especially if you prefer to be outdoors as much as possible (ie. Enjoy some heat / sun when fleeing from winter weather at home!). The many mirrors on the walls in the room bring in plenty of light and the view down Calle Larios and to the Larios ‘Mansion’ from the window over the kitchen counter is nice. The fold-out bed is very comfortable and we enjoyed many hours on the terrace overlooking the square. The sunsets really are spectacular.
The location is excellent as you are truly in the heart of the historic area and is a perfect spot to watch all the activity on the Plaza below. Just below is a bakery, La Canasta, where cafe con leche, bread and an assortment of delectable pasteries are easily available. A Carrefour Express grocery shop is down the street and is usually open until 10 at night, and Cafeteria Framil (if you want good coffee, breakfast sandwiches or Churros) is a few steps further.
We never had any hot water issues in the shower, even with two of us showering in succession, but did not take lengthy showers. The bathroom is tiny so would not be comfortable for a larger person. The washing machine is in a closet off the terrace and there is a good drying rack provided.
Other reviews are accurate about the stairs (6 floors and more narrow at the top) but if you are in moderate shape, it is no problem. We travel with backpacks (22-40 litre sized) and went up and down, sometimes multiple times a day. We never took the elevator except down the final morning when we left because of the additional luggage we had acquired given gift-shopping.
Provided you don’t mind stairs and are really looking for a pied-à-terre, this is a a perfect spot!
