We had a nice stay in Malaga. The apartment is beautifully located in the center of Malaga. Everything is within walking distance. Of course it is sometimes a little louder than at home, but that belongs to the south. Everything was clean and beautifully prepared.
If you only want to visit Malaga, don't take a rental car. As described above, you can reach everything on foot. The multi-storey car parks are very narrow and expensive.
