We are from Germany, and a very relaxed couple
Mathias and his friends (they were 10 instead of 8) were very nice and very calm as i asked them. He said he asked me but i answered him that's the flat was made for 8 persons. i think we misdunderstood each other because of the language... Anyway it has going well and i didn't have problems with the neighboord.
It was a pleasure to host Matthias and Julia, they were so nice and left our apartment in perfect condition. We would highly recommend them as guests.
