I just spent a few days in the studio and had a great time. The location's good, within 15 minutes of walk to Palermo Soho. It's just beside a metro station but I ended up not really using it as that line didn't really go where I wanted and cabs are very cheap. It was also an easy intersection to give as a destination to cabs.
The studio had everything I needed and more, the pool is nice.
The only thing would be if you're very sensitive to noise it may not be the best place for you, as it's just beside a big boulevard and there are many buses passing on the street right in front, until pretty late. But Buenos Aires in general is very noisy!
