What can I expect to pay in terms of rent for an apartment in Buenos Aires?

I am looking for an unfurnished 1-bedroom apartment or studio, ideally around 50 square meters and in Palermo or Barrio Norte (all though I would definitely take other safe barrios into consideration) for an indefinite period of time. The ads for temporrary furnished places you find all over the place are not helpful in this regard. What would an apartment like this typically go for, including all extra costs (cleaning the stairs, taking away the trash, taxes, utilities). Yes, and I know it's hard for foreigners because I own no property in BsAs, but I would put up a big deposit if necessary.
