Great spot - Palermo Hollywood is fantastic in general - and close to lots of good bars and eateries.
Apartment is nice, Florencia was very responsive and lovely (didn't meet but we had to get in touch a couple times in the two weeks we stayed), all around positive experience. Was great having air conditioning to escape to after a long day walking around too.
Also, recommend going to a highlight of our stay which was close by, Tierra Negra cooking class.
