I had the pleasure to stay in Susana's studio in Las Cañitas for the last month. The apartment is really lovely, very clean and Susana has made sure that it has everything that you might need for your stay. It is very light and has a great balcony full of plants that overlooks a leafy and quiet street. The bed is really comfortable and as Susana mentions there is plenty of hot water! a rare find in BA.
The area is really lovely and there are heaps of cafes, restaurants and supermarkets nearby. There are also plenty of options for public transport nearby. I thoroughly enjoyed my stay and meeting Susana, who makes an excellent host who is always available to help or offer advice on the city.
I'm would definitely stay here again and recommend the studio without hesitation.
