Anna wasn't available when we arrived, so Nayara welcomed us in the appartement. His English is not perfect but we managed to understand each other (he's very nice).
The appartement is as advertised on airbnb. Everything is new and of superb quality, although some things were missing (shampoo, soap). However, the location is amazing. The beach in front of the appartement is way, WAY better than the one next to the center of Malaga. For the week we were there, we never had under 25°C even at night (went up to a whopping 40°C during one day), so... beach everyday !
To get in the center you can use the boardwalk next to the beach (30 minutes), or a taxi ( 8 euros). There are some nice bar/restaurant next to the appartement but I'm not gonna lie, some restaurants in the center serve amazing food and cocktails so it's worth the walk. At night the city transforms itself to become even more beautiful. Bars and pubs fill up and stay open very late (3-4am). There are not many nightclubs worth going (Metrica being an exception if you like german/british techno/house music like me), so I wouldn't recommend going for clubbing. But there's no really need for that since the bars open up until late.
Overall we had excellent holidays and we would recommend this appartement. The city is more than worth seeing.
