Maria's apartment is absolutely adorable! It is modern and sweet and they've made great use of a small space. I imagined myself living there in the heart of Malaga - really so nice. It is right smack in the centre of everything! So it's a perfect city location. We only stayed one night and we didn't go to the beach but we were in Malaga last year so we know the beach isn't more than 10 minutes walk away.
Maria is also a great host - she answered our emails promptly and was there to meet us and show us inside.Of course, because it's right smack in the centre, it is fairly noisy at night. The big doors / windows in the apartment do a decent job of blocking out the worst of it but you can still definitely hear the party people making their way home and having fun in the streets. This is to be expected with this location, however.
If you're looking for an exceptionally clean, cute, cozy apartment for two with all the modern amenities you could need and where you can just step out the door right into the thick of things, then definitely stay here! We would love to stay here again if we come back to Malaga for a third trip!
