The room has exactly what you need. A bed and a wardrobe. The building is located in a central area, and thus the balcony has an amazing view and besides, everything is easy to reach. However, it can be VERY loud outside. We slept 3 nights here and during the first 2 we woke up again and again because of the noise, until 5 A.M. I've heard this is an issue in all Malaga, but especially if you stay here, I recommend you buy some ear plugs. (You also can't close the balcony's door because it gets way too hot, at least now, during summer, as there is no air conditioning)
The shared kitchen has all you need (with the exception of an oven, but it has a microwave). It is rather clean. The hot water in the shower is intermitent.
We had a problem with the cleanliness of the bed sheets, told the owner and they were changed, but it was very unpleasant. As they are currently aware of the issue (that could be from the detergent used), chances are they will solve it.
Overall, staying at this room you get the minimum service for the minimum amount of money in Malaga. However, if you encounter problems, the owner is responsive.
