Yes, I have googled it before posting my reply (to confirm the details of what I was sure of: there are limits).

This is part of the FAQ/information forms when asking for information about moving in a EU country for EU citizens.

As an EU citizen, you have the right to move to any EU country for a period of up to 3 months as long as you have a valid identity card or passport. If you want to settle in another EU country but you have no intention to take up any work or education there, you need to prove that you:

    have sufficient resources for you and your family during the time you want to stay in your new country

    have comprehensive health insurance

Reporting your presence and registering your residence

During the first 3 months of your stay in your new country, as an EU citizen, you cannot be required to apply for a residence document confirming your right to live there - although in some countries you may have to report your presence upon arrival.

After 3 months in your new country, you may be required to register your residence with the relevant authority (often the town hall or local police station), and to be issued with a registration certificate.

You will need a valid identity card or passport and:

    proof of comprehensive health insurance

    proof you can support yourself without needing social assistance benefits: resources may come from any source, including from a third person.

Can you be requested to leave or be deported?

You may live in the other EU country as long as you continue to meet the conditions for residence. If you no longer do so, the national authorities may require you to leave.
