Walter's apartment was perfect. It's located within walking distance of 2 subway stations and there are plenty of restaurants and supermarkets nearby. It's also within walking distance of a few tourist attractions and just a few subway stops away from major parts of the city. The neighbourhood was pretty quiet and I felt very safe. The apartment is very clean and has everything you could possibly need. There are 2 bedrooms, 2 bathrooms, a fully equipped kitchen with a washing machine, a living room, and balcony. Walter was also very welcoming and helpful, and quick to respond to my messages. I enjoyed my time at his apartment and would definitely stay there the next time I'm in Buenos Aires.
