Excellent place to stay is buenos aires!
Charming and all new, very nice modern building, tastfull decoration and close to the best area in the city, with lots of great bars and restaurants.
Plus the extra facility with the little pool on the rooftop and nice 24h doorman are great.
Emilce is really arranging and very nice. We could add an extra night easily and just shut the door and leave the keys as we had an early flight. Would stay there again definitely and recommend it to friends!!
