I came across Vain Boutique Hotel by chance in a last minute effort to change hotels in the same night due to poor conditions.  Fortunately Vain had a vacancy and it was near the hotel I was leaving.  It was 11pm when I made the reservation online and they were waiting for me when I arrived 20 minutes later.  Very friendly staff!  The room was more than I expected.  Very clean and modern with a refrigerator, bottled water and wine to purchase in the room.  It had a small patio but the best part was the comfortable bed and the shower that had a complete glass ceiling.

There is only a few rooms per floor.  On the second floor is a common room that was comfortable and modern as well.  This is now my go-to hotel when ever in Buenos Aries.
