We had a fantastic stay at Marián and Manolo's place. It's a large, spotless first floor studio apartment with a separate sleeping area and a sizeable terrace that faces the internal courtyard - it didn't get any sun in November but it was mild enough to sit out and have our morning coffee there anyway which was lovely.
Marián and Manolo provide everything you could possibly need for a short break including towels, a hairdryer, coffee machine, coffee, tea and cooking basics. The location is great, a minute's walk from Plaza de la Merced and near a couple of supermarkets and plenty of tapas bars but not in a noisey spot (the apartment doesn't face the street anyway). Marián and Manolo gave us some great recommendations and were always on hand if we needed them.
The apartment building was secure, clean and usually quiet but we think one of the neighbours must have been smoking in the hallway as well as sometimes there was a lingering smell. This is a shame as it's no fault of our hosts but is the one downside if you're a non-smoker. You can also sometimes hear the neighbours as the walls are quite thin, but it wasn't usually a problem as it was a pretty quiet building - it only happened one evening and once or twice during the day.
We had a great stay and would definitely stay at Marián and Manolo's again if we came back to Málaga - great location, cute apartment, wonderful hosts and has everything you need :)
