It says very clearly on my host-profile that I charge 10 euro for bedlinien for people just staying one night, if they don´t bring that themselves.
However, after your long and tiring argumentation about this, I no longer rent out rooms for one night only. It is very boring having guests not being able to accept the houseroles that is communicated both on the web and in e-mail, upon arrival.
Fixing the intaernet-supply when there is an occasional weak supply in the area is something that should be taken care of by an internetoperator, most people understand that. That is nothing that a ordinary user can fix themselves.
However internet by cable worked well and you were offered that as soon as you walked through the door, which your friend happily used.
When it comes to using my private area, it occassionally happen that I invite people living here to join me there. However, people who cannot read my houserules about my house being a vegetarian, organic house and instead, bring there awful McDonald take-awayshit here, destroying the odor in my house for days and filling the garbagecan with tons of disposable garbage, are certainly not invitet to my private areas and should not come to my house at all.
