I loved staying at Lucas’ place, it is very central to the Metro, Obelisk and is located right on Corrientes Avenue. Lucas was very attentive and answered all of my questions. questions promptly and even explained to me the laundry availability in the building and was very patient.
One drawback of this area is that it can be a bit loud when the theatre shows get out around 11pm with cheering and honking outside that can be heard even from the 25th floor! But that was only a small issue for me and it was offset by the very convenient and vibrant location! I would stay here again if I return to Buenos Aires.
