We visited Malaga as a family in Dec, and stayed at Andrea's apartment for 10 days.

location - the apartment is comfortably located at the northern end of the old city, which is an ideal location because almost all interesting sites and venues are within a short (2-16 mins) walking distance, but the neighborhood itself is very quiet and not spoiled by street traffic. we ofuind it without any problem using google maps, and arrived from the airport there by taking the train (15 mins ride, super cheap) from the terminal to Alameda Central. from there it is a 20 min walk through the streets of the old city to the apartment. 1-min walk from the apartment there is a grocery shop which we visited frequently to buy water and snacks.
The apartment - for us there are a few things that really matter in any place we stay in - the kitchen (we love cooking), the bathrooms, Wifi and beds. the kitchen is in a seperate room with a window so perfect for cooking without getting the smell into the rest of the rooms. it is nicely equipped with just what one would need for cooking - we prepared a sea food soup, mushrooms sautee, toasts with Jamon and cheese - all without needed anything beyond ingredients which we purchased at the main market downtown. the apartment has 2 bathrooms - each with its own shoer and toilet, which is naturally very convenient for parallel use. plenty of towels were supplied, much more than we needed, but also shampoos and soaps (hand and body), which was a nice touch (although we brought our own, being picky about the ingredients). the Wifi worked flawlessly, both at the living room and in the master bedroom - we were watching films on Netflix and did several work Zoom calls without any interruptions or jitter. the beds - we expected cheap IKEA beds with unstable bases and overly soft matresses like we usually find them in airBnB apartments, but Andrea actually invested in high quality beds and mattresses that positively surprised us and made our sleep deep and long, "better than home" as our child said.. there is no laundry machine in the apartment but on the small street in which it is located there is a 24/7 self service laundromat which we used twice. we rented a car for 3 days and used the convenient carpark inside the complex without any issues.
host - Andrea welcomed us personally upon arrival and gave us all the necessary info including a quick tour to the rooftop pool and the underground car park. we then sat down with him and asked tons of questions about farmer markets, restaurants, best beaches, flamenco shows, tapas bars and places to visit around Malaga. Andrea used a city map to patiently write down his personal recommendations of places. many of them were far from trivial and not found on your typical go-to travel websites. we followed his tips and found them invaluable and of high quality! half way through our stay, Andrea gently asked if we require anything and whether we are ok, which we found very thoughtful. we had absolutely no issues, but the filter in the water jug supplied with the apartment seemed a bit old so we asked him if he has a replacement somewhere in the apartment. Andrea simply came the next morning and hung a plastic bag with a new water filter on the door.. finally, we Andrea gave us extra time for a late checkout so we could keep our bags at the apartment while waiting for our afternoon flight back home. he was always available and responded very quickly.
