You have several options for trading BTC/EUR and your choice will depend on your preferences. Id advise you to try one from these 3 platforms: Bitstamp, EXMO, or CEX.IO. They all are European-based cryptocurrency exchanges that means EUR deposits via any kind of payment method is easier than using other platforms. Those who use SEPA payment will be happy.
Personally, I prefer Cex because of high security, diverse payment methods including SEPA, and easy to use interface:

The limits of deposits and withdrawals depend on the level of verification. It says about compliance with regulations and strong security.
