Excellent place. The location is close to everything and well connected to public transport, and the historical center is a few minutes walk away, but unlike many other places that close to the center there is no noise from traffic or partying tourists. The apartment is in a quiet residential area near a sports facility. The two windows both open into the courtyard, which provides shade and further sound isolation too, so you don't get hot sun into the apartment during the day. While we were there there was heavy construction happening across the street, but it was quiet inside. The only noise that made it through were the nearby church bells. There's plenty of supermarkets and fruit and vegetable shops in the area, as well as a covered market a few minutes walk towards the west which is the best place to get fresh ingredients. This is great because the apartment has a fully equipped kitchen.
The apartment was clean, and had everything we needed. The host allowed us to check in much earlier than indicated, which was extremely convenient. Communication with the host was great. Everything was as shown in the photos. There's a surprising amount of storage space - a wardrobe as well as three large drawers opposite the bed and three smaller drawers under the TV (one is in use for cutlery). We didn't use the TV. The internet connection was very fast and worked well. The fridge had an enormous amount of space. The bathroom was good, though water pressure dropped off while the toilet was refilling. The hot water took a minute to get through the pipes, but worked fine after that. There were two ceramic/infrared hotplates in the kitchen, two coffee machines (one drip/filter machine and one nespresso capsule machine), and a microwave. There was no water kettle, but boiling water in a saucepan worked fine. The tap water is chlorinated in Malaga, so if you're coming from a place where that's not the case it might taste strange. In that case, leaving it in the fridge in an open bottle for a few hours will dissipate the chlorine taste. You have to walk up one flight of stairs to get to the apartment. The only negative thing we experienced were some mosquitoes that felt as much at home as we did, hid away on the high ceilings during the day, and came down at night to bite us. Other than that, everything was perfect. Definitely recommended.
