“While showing its age, the hotel offers comfortable beds, pillows, and reliably warm showers; the air conditioning could be more effective for larger rooms. Its location near Avenida Corrientes and Pizzeria Guerin is a definite plus for experiencing Buenos Aires; for the price, it's a solid choice.”
