The Mio Buenos Aires was a beautiful, nice boutique hotel. Great pool, sauna and steam bath on top floor, very helpful and nice staff, and a great wine selection. We did not eat here, though the steak house looked very nice. The wooden bathtubs are part of what made me book this as they are so unique and beautiful, but I would say a bit impractical and sadly a little smaller than I would have liked (though I'm 6'4" and 220 lbs, so....). It also is very near many of the things you'd likely want to see (i.e. Recolleta Cemetary and good dining near that). However, the city is so big with so much to see, you'll still need to Uber or drive to see much of it.
