We've stayed for a week in Malaga and Cecilia and Jesus we're from the very beginning very helpful and friendly. They gave us tips regarding the local must see's and answered instantly back if we had any question.
The apartment is great and located near to the beach which is awesome. There is also a nice park to walk through and many bars and restaurants nearby which are really affordable. The area around the apartment is not very touristic so it's quite and domestic. This also means that most of the people speak spanish at the stores but there is always a way to communicate with each other even if you don't speak the common language.
All in all it was a great experience and we would totally recommend this apartment and Jesus as a host. Also Malaga is a great city to visit. For further travel a rental car is easy to get at the airport (we rent our car at HelleHollis which is quite near the airport - good prices).
