The flat is very well located, some 10/15 minutes walk from the center. (You could for sure visit the center and return for the siesta midday). Also, the flat is located in a neighbourhood with many shops nearby and the area is very safe.
Overall, the flat was very clean and we had everything we needed : the bathroom is big with a nice bathtub, the kitchen has everything you need if you want to make your own food.
Marco is a very nice host who welcomed us and tried his best.
I'd definitely return to his place for my next trip in Malaga!
