We spent 10 days in the flat and it was great: the flat is quite new, it contains all what you need, including cot and highchair for our baby.
It is super clean, in a nice building, super well located, in the heart of the historic centre. Even if it is located in the centre, you do not hear street's noises.
Silvia is a great host (probably the best one we ever had!): she has an answer for everything! she booked a cab for us, gave us tips to visit Malaga, found a solution for the microwave which was not working anymore (because our son played with it 🙄) and sent us back home what we forgot in the flat.
We were able to check out later since our flight was at 8pm and there was no other guests arriving the day after.
We strongly recommend this accommodation if you visit Malaga!
