First things first- flat and the building itself is amazing!
More in detail - access to flat is easy, the flat has everything to comfort you in short to long term stay as we spent 3 weeks and felt like home every day. Each room has huge windows and new AC's. In bedroom there is spacious wardrobe , comfy bed , TV.
In kitchen there is everything to cook. Internet was fast (100mb/s) but some times did lost the signal for minute or so ( max few times a day).
The building offers access to 2 swimming pools (inside and outside) which are in fresh condition all newly built, sauna, Gym, washers and dryers downstairs (for extra charge) and 24/7 security guards which were very welcoming and positive. Area is safe and easy to reach restaurants and metro by foot. We found some nice places closeby to eat: Pani, Birkin and Gratitude. 2 min walk away there is small Carrefour Express and Coworking (Huerta), if you want to take metro (subte - green line) closest station is 6 min away.
Claudia was supportive and responsive, we recommend this stay as it offered more than expected
