Flor is a great host and this is a great place to stay in Buenos Aires, it is in a great neighborhood, safe and a short walking distance to everything you might need bakery, supermarket, etc.
This place is also great if you're considering visiting Don Julio Parrilla the #1 restaurant in Buenos Aires, it was just a short walk.
I have to mention how attentive Flor was, she able to accommodate my check in and check out. This place is better than any hotel around this area.
