Carlos apartment is well worth your money- clean, comfy and very well organized. Carlos himself is just as organized and will always be attending to whatever needs you could have.
If there is one thing I would have liked to know in beforehand it would be the location- in other words and in regards to the city center, the beach and any other sights it is perfect, but to take maximum advantage of the apartment you either need a car, or be training for an iron man. Some parts of Malaga are steep, which gives you good views for sure, but without a car it also gives you exercise, desired or not.
All in all an absolutely great place to stay!!!
