The best option in Buenos Aires! I've changed a dozen apartments, but this is where I dream of coming back next time.
First of all, it's the Gated Community.
Secondly, it's big even for four people! A huge terrace overlooks a quiet and peaceful street (and a cafe where you can go down for breakfast right in your bathrobe).
Thirdly there is both a washer and dryer and a dishwasher!
I'll bet you won't find similar conditions at a very reasonable price. And, given the wonderful and understanding hosts, it's a win win!
