Response from Julia:
I'm so sorry about the bad smells during your stay! I just want to make clear that they are not a standard feature of the apartment. The smell in the bathroom is gone now, and was caused by the neighbors burning some food--the window in the bathroom opens into a shared air shaft, so the smell came in through there and then decided to camp out in the bathroom for a couple of days. The smell in the elevator is totally new--I've talked to the super and the elevator is going to be cleaned. So it shouldn't be an issue in the future.
