Álvaro has been the most attentive host I have met on AirBnB.
The loft was awesome, we especially enjoyed the roof top with the pool.
Location is in the heart of Bellavista with all the restaurants and clubs right around the corner.
I am a sensitive sleeper, but with the windows closed and ear plugs I was able to fall asleep every night (Sun-Friday) despite the proximity to the clubs.
