We stayed in the Manquita room for a night on our way through Malaga. It was a large room, one of 5 within the apartment. Self-check in was easy and the apartment is less than 5 mins from the train and bus stations, which were our routes in and out. We also walked to the beach, and to the centre of town.
There are two bathrooms, each nice and clean, with shower, toilet and sink. We didn't have to wait for them at all, so sharing was no problem. The kitchen was also large enough for more than one guest to be in there, though we only made a cup of tea.
The only downside is that the big solid doors to each room are heavy - good for security - but also noisy. A few people seemed to be in and out of their rooms during the night.
Great for a quick and really well located stay.
