My friend there also had to have a local allow her to use her DNI to get that App to work. They really should fix that if they want tourists to use it. Bummer about the dog poop. That is what my friend told me. She said you have to be very careful. I guess they weren't teasing me and it is true. A shame a beautiful city like BA wouldn't have people picking up. Great about Recoleta. Maybe I will stay there instead.That's a good question, I would say the Ecobici app is the one negative. I could never have figured it out on my own, and it took my local friend using his own passport, credit card and DNI to get it done on my phone. Once you get it the app works great every time, never had a problem getting a bike instantly, but getting the app is an unholy pain. My friend from London speaks enough Spanish to understand what it's asking us to do, but it simply doesn't work. It's a terrible shame.
One other negative I guess is dog poop. It's not on every block but there's enough (especially in Palermo) that you have to watch where you step. It doesn't bother me very much but it's an eyesore on an otherwise beautiful and fabulous city. Recoleta doesn't have nearly as much, in fact I can't remember seeing any.
