Very cozy place, the pictures don't lie! The interior is very tasteful. Yes, the theme is "antique", but contrary to what some reviews suggest, everything was very clean and functional. Also, the TV is now a flat screen, if it matters (it didn't to me, I never turned it on). The AC is wall-mounted and works very well.
The neighborhood is fantastic; the close-by market a gem! To my surprise, even when on the terrasse, I couldn't hear the traffic on the nearby Av. 9 de Julio.
Important for me: even though it said in the description on the Airbnb site "smoking allowed", the place did not smell of smoke at all. On the instructions I received upon arrival it clearly said "Smoking not allowed", so maybe the info on the webpage was outdated or simply erroneous.
I'd definitely stay there again!
