We stayed at Myra's apartment for a month (December 2018).
Pros: Safe neighborhood. Cute and comfortable living room with big couch that is great for sleeping on when the bedroom gets too hot :)
Some great cafes/restaurants nearby : Cocinarte, Acacia Negra Cafe, La Farola, Pizzeria Don Ignacio (for empanadas)
It is close to Parque Elcano, which is a relatively nice park for working out and hanging out. I thought the cemeteries (Cementerio De La Chacarita, Cementerio Aleman y Cementerio Britanico) were super cool.
Cons: AC system is old and cantankerous sometimes and does not reach into the bedroom, so the bedroom can get pretty hot and stuffy. The shower water was unpredictable (we let Myra know about this). The smell from the neighbors smoking cigarettes drifted in the bathroom window every day.
It really is "vintage" in a lot of ways. :) Don't expect a modern apartment.
