Rare for Argentina the breakfast included a hot entree ie scrambled eggs, that were hot,soft, creamy and silky smoothe. Good variety almost Brazilian in it's variety.
The room was nice, clean, comfortable, with a bathtub.
My only quibble is that is was indeed a single bed, rather narrow. I don't see a portly guest being at ease on a bed that narrow. In my country it is rare to see single beds these days.
But all in all, a clean, comfortable, well appointed hotel with an excellent included buffet breakfast and good location.
