I spent 11 nights in this lovely place with my elder mother. Everything was great and very clean. I have difficulties with cockroaches and I didn't see any in the flat or in the whole building.
The balcony was lovely, although it was noisy in the evenings, because the flat is at the street of bars. But that is Spanish way of life: lively and loud. :)
It was really great that when you close the windows and the door to the balcony the flat gets really quiet; it was amazing.
The street is lovely, and lively plaza de la Merced is just behind the corner. My mother just loved to sit there and watch people. There are two theaters in the same street: a theatre of new plays and a more traditional; I enjoyed that.
What can I say more: Go and experience it yourself! We loved the apartment and it made a good ground for that we fell in love with Málaga.
I definitely will be back.
