This apartment is in the Plaza de la Merced, so is right next to the main old town and cathedral. In this way it was really well located for walking in the city, and had a nice view up to the Alcazaba. However, being central and right above the Plaza meant that at weekends when the entire Plaza filled up with young and loud drinkers in their hundreds, and motorbikes showing off, it was insanely loud. So, I wouldn't recommend it for a quiet city break. Also the same corner of the plaza is a refuse disposal site, so in the early morning you get the sound of the thousands of beer bottle drunk the night before, being emptied into the truck.
The apartment itself is a pleasant circular layout, but it stinks of cigarettes and drains, and the sofa was so filthy it looked like they bought it second hand from a bar. The standard of cleaning was low, with some kitchen items still dirty and the balcony was full of cigarette butts and ash.
I guess if you are in Malaga on a stag weekend or a binge drinking fest and you smoke, this place might be perfect.
