My girlfriend and I had a great stay at Calle Carreteria 109 arpartment 2. We were welcomed by our host Paolo on the first day and was given the short tour of the apartment. He is great at answering any requests or questions and he where flexible when we asked for the opportunity to stay an extra night.
The traffic might be an issue to some, as it can be quite noisy during the nights, and the wi-fi connection is not stable enough to rely on in case of the need to do some work in our opinion.
Overall the apartment is nice with great bath/toilet facilities and a servicable kitchen and very close to the inner city, the beach and sights of Malaga.
