it's ok--building is fine, rooftop is nice to go to, very close to Belgrano subte that will get you places, and you're close to Florida which is where you change money.
while the building is modern, the apartment is not--old, worn-out furniture, no microwave oven, not even paper towels, bed not that comfortable.
for the money, you can definitely do better (including within this building--I know from experience), but this is fine if you need a place and it's available.
