Loved this spot - super unique, interesting design, right in the absolute middle of everything in Buenos Aires! As other travelers have noted, it is noisy because it's right in the city center near the Obelisk, but with earplugs and an eye mask, my friend and I had no trouble sleeping. The beds were comfortable, the AC worked well, and overall the AirBnb was so comfortable. Cecilia, Fernando, and Luz made checking in very easy and simple.
The wifi was great here too - I generally got between 60-70Mbps down, 10 up, and I was able to work remotely very easily while I was staying here.
