I stayed with 2 other friends for a week in August and we had a very good experience. Location-wise the apartment is close enough to the train station that you don't need to take any form of public transportation to get there. On top of that it's located very close to a public beach where you can either rent parasols/sunbeds or bring your own. When we stayed there, Jose very kindly included a parasol and two folding chairs which we used every single day.
To get to the city centre we used an uber-like service which was quite cheap, but there is also a bus that can be taken.
In terms of amenities there's really everything one might need from fully equipped kitchen to a dishwasher, so we ate at home a few nights without any issues.
Highly recommended if you're looking to spend a few days in Malaga by the beach.
