Loved the location of this property. I found it to be Highly Walkable.
I have a luxury rental myself in Downtown San Diego, California (United States) and can be very particular when judging other units. https://www.airbnb.com/rooms/15124810?s=51

I gave Andrea's place a 5 STAR review. there are some minor things to improve but nothing that would hinder your enjoyment of this property and it's location. There is plenty of space for an individual or couple. since it's essentially a studio it might be a little awkward for more people than that. The bed is firm and comfortable. There is a nice balcony with a great view. The kitchen is adequate and will serve 95% of basic needs. The bathroom is fine and it comes with a bidet. (Caution to American tourists not familiar with a Bidet, the water shoots up at extremely high velocity, I almost lost an eye trying to figure it out. HAHA)
The walls are thin so you may hear the neighbors but they weren't very noisy and I probably disturbed them more than they disturbed me. I would recommend bringing ear plugs just to be safe and insure a good nights rest.
This property is close to parks, restaurants, bars, and the gym next door is fantastic. Andrea was there to greet me and made it very easy to check in. Too bad they don't have lockboxes in this area it might make it easier on her.
Don't hesitate to select this unit for your stay in Buenos Aires. I will be coming back!
