This is a fantastic apartment. It has everything you may need, and then some (it even has a "parrilla" (a BBQ grill to use with coal) in the balcony). The apartment has large windows and lots of natural light, fresh air, and all the appliances and kitchenware you may need (there's even a super handy laundry basket if you want to use the washing machines in the basement of the building). The wifi worked perfectly well. I never heard the neighbours, and there's very little street noise at night (I slept with the bedroom window open every night). Even though the apartment is not downtown, there are many buses and a subway line within 4 blocks with a super convenient and reliable connection to anywhere in the city, including all the main attractions, even late at night.
I will definitively book this unit again. Gabriela was a great host, she was very polite and kind, easy to reach, and responded almost immediately the one or two times I had a question for her.
