Our stay at the Recoleta apartment was very nice. We were thrilled with the location, on a major street with restaurants, cafes, small pharmacies and convenience stores nearby. The metro station is only a few blocks away but we did not use it. Recoleta cemetery (grave of Evita and an interesting place to visit) and a weekend market near it were several blocks away. All major sights were within an inexpensive taxi ride away.
The apartment was spotless. The balcony had a great views to the northwest and north that included the Rio de la Plata, and cool breezes. The beds were comfortable and the bath and shower worked great. The desk/security attendants in the lobby were very helpful. Taxis were plentiful in the area.
We did not use the clothes washer but you might find it useful and there were supplies below the kitchen sink.
We communicated with several hosts and all were helpful and responsive. Highly recommend!
