Share Netflix account with friends?

So my three friends and I have considered Netflix Premium for 15.99 euro per month to book. But is that allowed that we four would use this account on four devices? (Because we do not live in a household) Because actually we would legally book four devices and only we would use the Netflix account.

So? Is that legal?

In the terms and conditions is yours that one must have the same address but if that bothers anyway makes no one.
