I stayed here for a month and consider it the best of the 5 AirBnbs that I've had in Buenos Aires. (Many of those were in a state of disrepair).
The location is great, with lots of cafes, restaurants, green spaces, and a few bars very near. Many more within walking distance. The Ortiz subte is a 10 minute walk.
There is quite a bit of street noise, depending on the time of day, and construction nearby. Closing the doors and windows helps a lot, but the noise is still there. The smaller bedroom is quiet. There is very little noise from within the building.
The kitchen was equipped sufficiently for my needs, with plenty of counter space. The washing machine and hot water worked well. The 3 air conditioning units all worked well (after the one in the smallest room got its coolant refilled.)
There is a lot of natural light in the living/dining room and the larger bedroom.
The property manager was very responsive and professional--much more so than other Airbnb's here.
