Great location. Clean, with very comfortable beds, and I have back issues so this was important. The building is quiet. We felt very safe, walked to and from many great restaurants, such as Pizarra, Don Julio, Roux, and Casa Saltshaker. Many nearby cafes, and delicious chocolates at El Viejo Oso (where they give out samples!) Even at midnight, there were single women walking possibly vicious but very small dogs. Easy access to the Subte.
We visited in early June, and the weather was exactly the same as it was in Boston: mid-50's and breezy ( granted, it is usually much warmer in Boston, but not this year). We sat out on the sunny terrace with wine and cheese when it was in the low 60's.
Lots to do and see even off-season, and possibly easier to get dinner reservations - though maybe that was because we ate at the unfashionable hour of 8. We were there for a week, never made it out of Buenos Aires or to the flea market or to Teatro Colon. Next time....
