Help with Park Hotel in Buenos Aires?

I am going to Argentina this year. Four months ago I went to Brazil and had such a great time. Now I am heading further south and I hope I will have good time there too. Still, I need some help with hotels there. Do you know anything about Park Hotel in Buenos Aires? I heard that it should be quite fine for staying. Is that true? Is it expensive?

I went there a year ago and must admit that it deserves much more than three stars. The place is very clean, elegantly designed, breakfast is excellent, and the people there are really helpful (most of them speak English). Also, there are very good and inexpensive restaurants nearby so you do not have to worry at all about food. Plaza de Mayo and Plaza San Martin are very near, Florida Street also, I recommend this place, if I go to Argentina again, this is where I will stay.
