We stayed around 2 weeks in this apartment and we really enjoyed it!
The location was perfect, the terrace is really nice and give you a view of the Castillo of Gibralfaro, the Alcazaba, the Catedral and the Plaza de la Merced with its beautiful purple flowers in spring.
We had no issue with internet, the wifi worked well.
If we have the opportunity to come back to Malaga, we will defitenely stay at this place!
