Me, my husband and my aunt spent Christmas and New Year's at Matias & Carolina's apartment in gorgeous Palermo. It was very comfortable for 3 people. The building facility is modern, the location is fantastic with lots of shops and food options within walking distance. We also liked that it's a secure building with 24/7 security and very professional staff. If you're planning to visit Buenos Aires I would highly recommend staying there. Hope to be back!
