I'm so sorry you didn't let me know you couldn't find the other trash bin! It is located under the sink and we have lots of extra trash bags in the drawer to the right of the sink. We certainly don't expect guests to use that tiny trash bin next to the desk for their kitchen trash needs. The instructions for the trash bin under the kitchen sink were in the Apartment Instructions in our thread under the title Kitchen. I do wish you had let me know about this during your stay as I could have easily resolved this annoying issue for you! And by the way, the charge is not from us, it's from our house keeper because people kept leaving huge amounts of garbage for her to take out and she got tired of it and wanted to charge us extra for that, so we just ask guests to take out any extra trash but can leave the bags and bins that are already there filled for her to take out free of charge, just all the extra trash is what she objected to and what she charges for...I hope this explains the extra charge - but we also put this explanation in the Apartment Instruction sheet. In any case, we always ask guests to please communicate with us any issues or questions at all they are having so we can resolve them whatever they are - but if the guest doesn't communicate the question or problem with us, there's no way we can resolve it. :l I'm glad you enjoyed the rest of your stay though. Next time just let the host know if you have any qs or issues and they will be happy to straighten them out for you.
