The hotel is great if you would not mind giving away a little confort in order to have cheap quality time in Bs As. Although rooms were indeed smaller than average hotel rooms, it succeeded very well on its task of being just a place to hit the sack and take a shower. My room was clean and so were my towels/sheets, replaced every day. There's a great café just across the street and a complete supermarket nearby. AC did not work, I however asked for an air fan ("ventilador", in english Ben-tee-lah-der) which was rapidly granted. What breakfast lacks in variety it has in quality, excelent media-lunas, great orange/pomelo juice and strong black coffee. Very importantly, perhaps the biggest advantage of all, the location is superb, having almost all interesting places to visit a nice walk away.
I say you should save the money you would waste by having a small fridge in your room (which you will probably not use) and buy tickets for a tango show.
