Martin was a great host. Had lots to share and recommend about Buenos Aires, even took me to a restaurant where the locals eat. Very easy to communicate with him in English and fast responses through WhatsApp.
The bedroom has a wonderful view of the city. Great location, walking distance to public transportation and local restaurants and bars.
I felt very safe in Buenos Aires and the city was very easy to maneuver.
If you have time, add a day trip to Tigre. Great escape to this water town.
