(This is not the apartment we got, we were upgraded by the host)
We spend a very nice few days in Málaga, partly due to the apartment. It was clean and quiet, and one street across the historical center, so we didn't have to take transports to visit the museums or go to the beach. We had great communication with the agency, they took care of a technical issue with the shower just a few hours after I messaged them, and we were warmly welcomed!
I honestly recommend traveling with them :)
