Normal social life is fine as long as you:
-
keep the number of visitors reasonable,
-
respect quiet hours (generally 22:00–08:00 under Croatian rules),
-
avoid loud music and shouting,
-
do not disturb neighbors or roommates,
-
follow any additional house rules the landlord or building has.
Once a “quiet visit” becomes crowded or noisy, it is considered a party and becomes a violation of the contract.
