Josefina is a great host and helpful. While there were minor issues such as dirty blanket, etc., it wasn't a big deal to me as someone who stayed at many Airbnbs.
However, the biggest issue I had staying here was the noise. Despite I wore ear plugs and noise cancelling headphone on top of them to sleep, the noise from the neighbors were too much as the walls are extremely thin and noise was constant throughout then nights.
There were many nights where the neighbor's dog barking non-stop loud , very loud dance music partying noise, people coming in and out loud, in the middle of the night which woke me up constantly at night. I felt so tired during the day from lack of sleep during my stay here. On top of that, there were construction noise (i.e., drilling) throughout the day which was bothersome as I had to work remotely.
Unfortunately, due to above issues, I would not be staying here next time I visit Buenos Aires.
