We were 3 people and stayed there for 5 Weeks. It is a really comfortable and bright place. Especially the rooftop with the asado place was stunning. Also the living room with the TV was amazing and the Internet for working/Netflix was perfect in all the floors. In the beginning of our stay it was still beginning of spring but it was warm enough in the flat with the heaters and then with all the balkony doors in spring perfect for fresh air and cooling the place down. The communication with Ariana and her husband Sergio were super easy and nice. They are both very friendly and speak good english.
The area is perfect for brunch places and Restaurants. The appartment is 15 minutes walking distance from plaza serrano. The neighbours are friendly and not loud at all.
We can highly recommend it and are also thinking of staying there again soon.
