I stayed here with two friends and it was great. The hosts are extremely friendly and helpful, they where always on standby to help out with anything.
The apartment itself is great (clean, and well equipped), its located in the city center (pretty much close to everything). The beach is a mere 15 min walk away (which takes you through some nice areas of the city).
There was one down side (if you can even call it that) is that parking in Malaga is quite expensive and there is no free parking available near the apartment (so keep that in mind ;) )

I would certainly want to visit this place again!
