Overall, we enjoyed our stay at Carlos' apartment. The location of it is perfect - it is very central and only 5-10 minutes walking distance to all the main attractions of Malaga. There are many restaurants, bars, cafes and shops around Plaza de la Merced, where the apartment is located. Carlos was a very helpful host and always available when we had questions or concerns. After the heating in our apartment had a malfunction, Carlos offered us to move into a new one next door immediately. Even though the apartment could be equipped a bit better, it looked exactly like it is displayed on the pictures and it was very clean.
The only thing that made our stay less enjoyable was the fact that we didn't get a lot of sleep due to the badly insulated windows. It was very noisy, especially at night - the street, on which the apartment is on, is heavily used by scooters and the people at bars around the Plaza de la Merced also cause a lot of noise. It was basically as if there were no windows at all. It is also worth mentioning that there is quite a bit of renovating taking place in the building, which adds to the noise level.
