Nice and cozy apartment ideal for two.
If you travel to Buenos Aires for tango, it is in walking distance to many milongas in Palermo.
The hosts are very nice and discrete people. Cristina doesn't speak english, but her husband Ernesto does. He can even help you with getting to the city from the airport and currency exchange.
Looking forward to my next trip to Buenos Aires. I know where I'll stay.
Gracias!
