I recommend accommodation of Carlos.
First of all, Carlos is very polite, friendly and respectful host, I was glad to chat with him. We didn't see each other because I did checkin by myself (get a key on a reception). Carlos let me do early checkin and I used that opportunity after looong flight.
Second of all, apartment is equipped with everything you need. I lived 1 week and I spent amazing time in Recoleta, BA.
Comfortable bed, A/C, kitchen, microwave oven, toaster, amazing view from a 21th floor balcony, very save district, there are a lot of markets, restaurants.
I just wanted to say "thank you" to Carlos!
