Hi there,
I'm moving the 1st of february from the apartment I'm renting now, is located in a lovely house in Palermo Soho, completely renewed, quiet, well decorated, very safe and close to Plaza Serrano and all this nice area. It has 1 bedroom and the kitchen area with dinner table, very special and authentic I have to say.
The good here is that you will safe commission and deposits because is rented directly by the owner (also my friend). I"m moving because I need something bigger for my husband and me as we are already one year living here and have different plans, but the apartment is lovely, I'm just helping my friend to bring nice people here as she is too busy working ;-)
The rent is $700USD a month and includes all expenses and cleaning service 2 times a week (but I think you can negotiate with her a bit). If you want more info, send me an email and I will send you some pics I have and all the details.
Good luck!
