We had a lovely long weekend at this apartment. Initially we were apprehensive about it being on a main road but the the traffic noise didn't disturb us on the 4th floor. The bedrooms, on the other side of the building overlooking the internal courtyard, were extremely quiet. The beds were really comfortable and the apartment very clean.
It was a good location on the edge of the old city - we found a left luggage store just around the corner which was great for a late flight home.
All in all a good apartment for use as a base while exploring Malaga.
