Marina has an incredible airbnb, one of my personal favorites in Buenos Aires and I've stayed at half a dozen.
I was greeted by Gonzalo, a person close to Marina who helps manage the very cozy airbnb. The apartment is immaculately clean and well decorated. All the furniture, appliances, and cutlery are in fantastic shape. On top of that, the apartment feels like it is truly a home and not just another airbnb. They do this not only aesthetically, but also through details such as fluffy towels, lots of comfortable pillows, dimmers, and little lights.
The airnbnb is a studio, but it is set up to almost feel like a small 1-bedroom. The kitchen is not visible from the bed, not even from the couch. Although there is no balcony, the apartment extends past the natural confines of the building, making it much more spacious that your usual apartment. This also provides a lot of natural light at all times of the day.
I stayed here for an extended stay, and would stay again.
