First of all: why are you writing me in English if you are italian? Probably becouse the review is coming from your young canadian boy-friend?
I would like to aswer to only two of your point: you must be aware of our check in time through the good Airbnb site. The check out time is the only rule that every good guest has to due in respect of the host and of the other guest who are coming pretending a clean and refresh room! You were no respectable leaving the room almost one hour later (no 15 minutes!) We understand that your young boyfriend likes sleeping too much, but we would give you a suggestion: the world is plenty of young guys more nice than him! Run away as long as you are in time!!
We are always friendly and happy to have people from everywhere. It's happens few times we contact Airbnb directly about problems with a guest. That's happened about you: hard noise at first morning (6 o'cloclk!)... with many complains from the other guests that were still sleeping!,...up and down from your room to the kitchen at every time with requests of hot water, cold water, normal water, water,water in every type! ...., no way to clean the bathroom or even YOUR room becouse you still inside all the time ...what else? not even a goodbay when you left! I send a private message to Airbnb about your bad behaviour and I know they advised you about it during your stay!!!!!!!!!!!!!!!!!!!!!
