If you have to stay in Buneos Aires, this hotels is one of the best options. It has reasonable rates for Buenos Aires, although is more a 4 stars than a 5 (for european or american standards, but this happens in all Argentina).
The rooms are great, big and the bed is superb!! One of the best beds I had sleep on. The bathroom is also great, with separate baththub ans shower. The only incovenient is the door of the shower, that doesn't close tightly and some water can run over it. Otherwise, I loved the low lights next bathrrom door and the lavatory, great at night!!!!!
The only "big" problem in rooms are the windows (not soundproof), as it's in a big avenue with lot of traffic, it can be annoying at night.
The breakfast is good quality, and maybe the only con is the dinning room, really small and next to the lobby, with all the tables too much close one to the others.
