This modern apartment was perfect for my stay in Buenos Aires. It's in a great neighborhood, close to lots of restaurants, parks, and public transportation. All the amenities are provided and then some, such as the backyard patio. However, if you're a light sleeper I highly recommend bringing earplugs.
I never met Herman in person but he was always quick to respond and answered all my questions. Self check in/out was easy too. I would definitely stay here again, if I'm ever in Buenos Aires.
