I stayed for 2 weeks and this studio was just what I needed. Communication with the host Maria was excellent all the time, she was very helpful and answered all my questions really fast although she wasn't in Buenos Aires. The location is great and it is spacious for a studio, especially with the private courtyard which is a nice detail. It was also very clean and I got a visit from a pest control guy who comes once a month to make sure any nasties stay away, which was good to know. The cleaning lady came at half-time and left everything spotless again. The warm shower worked great. The kitchen is well equipped in case you wish to cook. WiFi was also very good. If the washing machine is important to you, be aware that it is an older model and not very intuitive to use and the manual is in Spanish only. Once I got it to work, it washed my clothes perfectly. Also be aware that the apartment is rather noisy, the elevator is almost next to it and a car parking is just under it, you also hear a lot of noise from the neighbors until at least midnight, which seems to be normal in Argentina. This was not at all a dealbreaker for me but it might be for some.
