We (2 ppl) stayed for a week in Ana's apartment and enjoyed it. It is well located, you just need 5 minutes to walk to get to the old town (plaza Uncibay). There you can find a lot of tapas bars with good food for reasonable prices. A small supermarket is also 5 minutes away.
The building looked quite odd, but the apartment looked like the pictures. The apartment was big enough for two people, and well and modern furnished with everything you need. In the bathroom you even get some washing utilities. The kitchen was also well equipped. The apartment itself was very clean. It can be a bit noisy in the evening and the mornings due to the street in front of the house.
Ana and her husband were kind hosts and provided us with maps and information about Malaga. The key handover was flexible.
If you are going to visit Malaga, it is worth to stay at Ana's place! :)
