This was a great place, great location. It is perfect for 2 people, we enjoyed the location. Right in Centro Histórico, restaurante, shops, even walking distance to Malaga's Marathon starting and finishing line. The apartment has everything you need for a comfortable stay. The hosts are great.
The stairs are a bit of a hike on 4th floor, so definitely if you are fit, that is fine, If not, it is an exercise :)
I was aware of that because the host does remind of that in the descripción, so I was not surprised.
Overall, I was very happy with our stay, and would definitely return in the future.
