Response from Francesca:
The keys work perfectly. I'm using them since two weeks without any problem. You didn't stay (email hidden), my friend Camilla went out and opened the door and you came in in no time. The only problem was the toilet broken, and i'm so sorry again for that. I was abroad and it was impossible for me to call someone to repair the toilet, that worked before my departure for holiday. You didn't pay your last night here. You are not honest and I also don't want to have you here again.
