A friend had to cancel her visit to BsAs at the last moment, so the apartment she was going to rent is available. If you are still looking for accommodations between October 28 and December 5, let me know. The two-bedroom apt. is located in Balvanera on Alsina between Pasco and Rincon, only two blocks from the Congress and close to the downtown milongas. I will put you in touch with the owner of the apartment.
