What a great place! The description & pictures are totally accurate. Very clean, comfortable and stylish with a lot of nice little touches to make the place feel homely. The views of the city are awesome, as is the sunset! (18th floor, so really high up). Pretty much everything is provided including coffee to get you underway, and there's a great Kiosko just 100 metres away to stock up on most things.
Cafe's and shopping and banks just around the corner, as is a main bus route and underground station - you are just off one of the main avenues in Buenos Aires. The main entertainment area of Soho is about 20 minutes walk, and the roads are wide and well lit at night.
I would absolutely recommend this appartment, and would stay again :)
