Not only would I highly recommend this apartment, I would also stay in it in all of my stays in Buenos Aires. The apartment is very nice, it felt very homely and had all the things I needed. The location is very good (which surprised me!), it's very well connected to other areas of Buenos Aires, through the bus or metro. And if you want to stay in the neighborhood, it's great as well, you find a bunch of local things, it's close to supermarkets and all the basic necessities. I believe it fits a party profile (like if you're into drinking and going out) but also the sleep-in profile (the neighborhood is quiet and the apartment is amenable with a great varanda). The hosts were nothing but great, super caring, answering all of my (sometimes neurotic) questions. Extremely available.
Two things I should note that didn't bother me but maybe should be taken into consideration: the wi-fi can be a little slow at times (but it worked fine with Netflix and all that) and there's no microwave. That was not a problem to me, but maybe it's important for some people. Personally, all I have are compliments. Great place. 10/10.
