If Belgium is ok check Unix-Solutions https://www.unix-solutions.be
I'm almost 10 years a customer there. (Colocation)
They have their own modern datacenter in Brussels.
Never been better before! Really satisfied with them.
I self host a few website in Amsterdam, I am on fibre out near Sloten though. The speeds for intra-holland hosting on your own is pretty good and comparably cheap. however I tried strato which was ok and also another place in lux instead.
I hate shared hosting so my experience hasn't been good. If you can tell us a bit about your site and demands let me know, you may be able to get enough power out of a very simple cheap home setup which I can help you configure
