Best location in Buenos Aires and a cool, little studio flat.
However, I would only recommend for short stays. We were suggested this flat by the Superhost after we enquired for a different, cheaper flat, but unfortunately it has no washing machine in the building, which is an issue for longer stays.
The swimming pool was also too unclean to use for our entire stay (6+ weeks).
The flat is pretty expensive compared to others but you really are paying for an excellent location with amazing food and drink options.
The superhost was often very helpful but some messages came with a slight delay of 2-3 days.
