The key to an enjoyable time in any city is finding a good home base. We were lucky to arrive in Buenos Aires and find a great hostel to stay in. I would highly recommend Hostel Estoril to anyone traveling to Buenos Aires. For around $15 you can stay in this well located hostel right on Avenida de Mayo.
The hostel is clean, comfortable, with many wonderful features such as an on-site bar, huge rooftop patio, free baggage storage, free internet, a kitchen, very affordable Spanish lessons, phone cards, and much much more! The staff are very helpful and friendly, and they made us feel very much at home.
