Hey,
Yeah it's in San Telmo.
Its a good place, 10-15 mins walk into florida ave. Its a very safe, modern and friendly place. 4 bed dorms for 50 pesos a night. double room by yourself if that your thing for 180 pesos.
Free tango lessons at the hostel on tues and fri.. BBQ (parilla) nightly for 45 pesos including beer, staff are the best I have come across in Buenos Aires! Book in advance and it's a popular place...
As normal in Buenos Aires you need to be a little careful at night with your money/credit cards just in case you run into undesirables. Don't be flashing cameras around and wearing flashy watches. This is normal for touristas!! Just play it safe and don't bring unwanted attention to yourself and you will be fine.
a taxi (if your too lazy to walk) into say Recolletta is around 10-15 pesos depending on the cab driver. If he see's that you have no idea then you will go the scenic route! But shit happens and that's life in another country..
I have some suggestions for you!
Galerias Pacifico on Florida ave. (around 700 I think) is a very nice shopping mall. Downstairs is a great foodcourt so if you want to eat and shop then this is the place!
Manuel Tienda bus from the airport to your hotel. 45 pesos.. Great service by modern bus.
Change your money in the airport just outside the bag xray on the right hand side. after you collect your luggage. (DONT use the cambio's near the luggage pick up carousels... Go past them and there is a small group of windows on the right hand side which is a bank. The rate is much much better and no commission!
Head for the best steak in Buenos aires... 2 options..
1st is desnivel Address is 858 Defensa ave (5 mins walk from hostel!) the best steak is 'bifo del lomo'!
2nd is La Chakra on corientes Ave.... taxi or 15 mins walk down plaza del mayo.
I have plenty of other tips so just ask if your stuck.
jay.
