I stayed at Lucio's place in Palermo Soho for 4 weeks in December 2022.
Lucio's apartment is spacious enough for one or two people for an extended stay.
There is a small kitchen (which I did not use), a living room with a sofa and TV, and a balcony door that opens onto a terrace with a couple of comfortable chairs, a small table, and plants and flowers. The balcony overlooks the pool (excellent: clean and spacious) and the gym, which I did not use but seems functional.
The bedroom is spacious, the mattress is very comfortable, and plenty of towels, sheets and pillows are provided. Two air-conditioning units provide plenty of cool air, which is needed during the summer. Laundry is in the building.
As for the neighborhood, Palermo Soho is lively both day and night (the apartment is very quiet, however), with many restaurants, bars, stores, gyms and supermarkets nearby.
Lucio was very approachable and helpful.
I highly recommend Lucio's place for your stay in Buenos Aires.
