I'm Dutch so I most often sell my bitcoin at bitonic for euro. 
Did it 2 times already.

Belgian here and I usually do the same if I'm pressed for time, their service is excellent and the money is on my bankaccount the same day, because I have the same bank as them.
If I have enough time, I usually go with Kraken because their fees are way lower.
Bitonic does charge a lot of fees and they've also raised their minimum withdraw quite a bit, was at 500 euros at one point in time even, now it's 'just' at 100 euros.
Bitonic is indeed a good service, better than litebit imo.
Since you guys are NL/BE. This option might be interesting for you: trade your BTC for Guldencoin on Bittrex and then send it to Nocks to trade it directly for euro's. You should definitely check it out. I have cashed/entered crypto's like this many times and the money is within a couple of hours on your bank account.
