The flat is extremely well located, just a 3-minutes walking distance from Obelisco and 10-minutes walking distance from the historic downtown (Plaza de Mayo/San Telmo).
It is relatively small but comfortable and large enough for two people, exactly as displayed in the pictures. It was also clean and well-equipped.
What's more, the host was super attentive and friendly, always making sure we were feeling comfortable. So I definitely recommend this apartment.
