The apartment is tiny, but rather than small - I would say cozy. Perfectly located in the center of the old town, just across the famous bodega "El Pimpi" and a few steps from the Museo Picasso, Malaga Cathedral and other places of interest - the 3rd floor and solid windows gave us peace and quiet when needed. For a few days stay we got all we needed and even a bit more. The whole place is immaculately clean and well arranged, and the wooden ceiling gives us a touch of that traditional Spanish vibe. As mentioned in other comments, both staircase and shower are quite narrow, so if you need a little more room to fit in - think twice.
All the other apartments in the house (one on each floor) seem to belong to the same owners and I guess are very similar to each other.
Key box check in makes late arrivals hassle free, also staff from the property management agency were kind enough to store our luggage after check out so we could enjoy our last day unburdened. All in all - nice memories!
