stan1162 Ive rented from Airbnb with the actual provider being Babel hotels suites and apartments in the past. They have many locations in Buenos Aires and they’re also available on booking.com. The unit was quite nice, newer building and I received cleaning daily. Since you’re looking for a place, perhaps you can take a look at them, their website certificate is outdated but there’s many other links to them and reviews as well if you do a Google search. Let me know how it works out if you take this route and explore.. curious if you could work out something with the blue. Best of luck!

update: since I’m currently in the US on Booking.com the Pay at the property no pre-payment rate comes up in USD, I don’t see a way of converting that to ARG. Since you’re currently in Argentina maybe that’s a way of working it out the Blue if it comes up in the local currency.
