I've spent a month in this flat and I really enjoyed it. It is amazingly located on one of the most exclusive areas of Buenos Aires,near practically everything interesting to see in the city.
The apartment is very well equipped, lots of light,even it's facing the back of the building, wich makes it very quiet all the time (very good feature specially for those trying to sleep after a long party night :))
Love the place. I will definitely come back another time. Very good value for money.
