I'm Argentinian but I am living abroad at the moment. I can confirm you that this flat is great in terms of its location and ammenities. The balcony it's super dreamy. Great restaurants and touristic points nearby. Will definitely come back in the future. Victoria it's a great host!
Just a detail: bear in mind that the pool has limited access due to Covid restrictions and in general would recommend using laundry service outside the building (the one just around the corner - Juncal street, it's brilliant)
