I absolutely recommend Custodia's place. It is in the old town but without the noise, you can walk everywhere and you are in the middle of all the restaurants and bars. The apartment was better in reality, very clean and tastefully decorated. Loved the coffee machine :).
My flight was delayed but Custodia's husband was waiting for me. He was vary responsive, friendly and welcomed me with a smile. I was given local tips and he even offered to call the Concert Hall for.
We will definitely be back, Malaga is a great place to visit.
