Stayed a month at Rosario's apartment and had a great stay. It is super central and safe, easy to get to, and back from, all the sights (3-5 Euro Uber rides). Walking distance to everything you need: Shops, restaurants, parks, etc. It's also convenient to the airport and motorways headed west.
Rosario was super helpful with recommendations on what to see and where to eat, and she answered all of our questions. We highly recommend this apartment!
