A bit of background on us... We are a pair of west (wet) coast semi rural Canadians in our early 70s visiting Malaga for a month. We chose Arantxa & Georges place for a Centro Historic European experience and boy did we score ! Their place is spitting distance , well maybe more like a stone throw from the main happening square of Malaga, it is bright and has a small fridge, washing machine, private bathroom and as a bonus a mini supermarket on the ground floor with a great staff. Having read reviews and knowing there was going to be more nocturnal sounds than the occasional foraging deer or hoot owl we, we came equipped with a compact sound machine which we purchased from Amazon (far better than ear plugs and not the only city we will be using it in).
Now I would like to address my fellow North Americans, Europeans are hip to historic centers. If you want a bright apartment it will be on the upper floors of the narrow streets and being "historic " the probability of elevators (lifts) is low, also you should be aware that in Europe the ground floor is floor 0 not 1 which brings us to the 81 steps to the apartment which has resulted in geriatric buns of steel.
In summation you would be hard pressed to find a more centrally located apartment with warmer hosts at a incredibly reasonable price point than this.
