Great place - loved everything about it! The apartment has everything you need and enough space to feel at home. The kitchen / living room is lovely and the roof terrace is amazing I you want to spend some time relaxing. Only thing is the street is quite noisy so as a light sleeper you may want to bring earplugs. But that is true for the whole city! And the location is perfect because it's so close to the subte.
Federico wasn't there when I came so his sister came and she was great, showed me everything and made sure I know my way around. Federico had prepared everything and even checked on me a few times to make sure I was okay. Great people great place - highly recommended!
