Wonderful place.
Neighborhood is filled with sweet elderly people - so you frightened foreigners can rest assured it's safe.
Wonderful restaurants abound.
Nice balcony.
There's a beautiful round window on the shower wall you can open up to get a bird's eye view of Buenos Aires during your shower. It was my favorite part.
PS.
IMPORTANT: You will have to physically hand over your keys at the end of the stay, you can't just leave them in the apartment and be on your way like a typical Airbnb. Factor in this time for your travel plans.
