Hello Martina, it was nice meeting you :)
With regard to the fact that you had to put your suitcase in the wardrobe, I would like to remind you that there is a storage room in the entrance, just in front of the main door, so you could have left your suitcase there so that it would not have been a problem for you.
About the toilet, there is not just one. There is also another toilet which is at the begining of the corridor (first door).
With regard to the noise, i dont know how it works in the US, but here we live in buildings surrounded by neighbours (above us, under us, next to us...), so we have to be respectful, just as we told you. However, one night we had to get out of bed to remind that to you as you were playing loud music around 2:30am while you could have used headphones so as not to disturb us while we were sleeping (because 2:30am is a sleeping time here, so in order to live and share peacefully, we have to respect that). Besides, some days when you came late at night you would speak with us quite loudly, what could also wake the other guest up.
Also, the waste basket would not be so full if only toilet waste would be thrown there, and not magazines, flyers and/or other papers that should be thrown in the main bin in the kitchen which is way bigger and for that purpose.
Apart from those issues, we hope that you had a good time here.
