Geraldine is an awesome host! I wasn't sure how long I was staying in Buenos Aires and needed to make multiple changes to my reservation while I was there. She was super accomodating.
The space itself is just like it looks in the pictures--clean, stylish, and comfortable. It's my favorite space I've ever stayed in in Buenos Aires because of the good feel--tall ceilings, super comfortable sofa, and cozy bedroom. Internet was good, and I appreciated having an actual workspace / desk with drawers.
The outdoor patio / terraza area is awesome although unfortunately it rained so much this winter I never got to fully use the parilla.
Although it didn't affect me, the only thing I'd note as a potential concern for older people is that the stairs leading to the loft are super steep. My mom (who's in her 70s) stayed with me for a week and it was definitely too steep for her--although it wasn't an issue because the sofa is also a comfy bed.
Would totally stay here again, and will miss this place!!
