Yes it IS the best place to live in Buenos Aires!
Spent 10 days at the apartment. Scheduling and payment with AirBnb was flawless. Rico and Nicolas are very proactive on email and responded to every question!
Our check in was a snap as well at the building which does have security. Really the whole neighberhood was lovely and we walked around at almost all hours. There is plenty to eat or buy very close to the apartment so pretty much anything you need is in a few blocks. We also used Uber in the city which worked very well.
The apartment is bright and lovely. We found it neat as a pin! It has pretty much everything you need except for a washer and dryer but there are coin laundries around.
The apartment overlooks the park (which like most of the parks in BA is under restoration) and Las Herras street can give you some road and traffic noises but that never really bothered me.
If you stay in BA this should certainly be an apartment on your list! Recommended!!!
