Julieta's place was great. I stayed there a full month. The location is one block away from the beautiful recoleta cemetary. One block away in the opposite direction are beautiful parks and greenspace with famous sculptures. It is maybe the most serene area of Buenos Aires and the mornings are a delight walking up through the parks. There are a lot of great restaurants in the area and a coffee shop, Constanzos, with a great staff, on the opposite corner.
Julieta is very accomodating and responsive. The building is unique and historic, and was where the employees of the British Embassy resided before the Falklands War. All in all I think it was a great choice. I ended up renting another listing they have next door for the following month.
