Exoscale is based in Switzerland and has a nice DigitalOcean-like platform. It also has configurable firewall settings where you add the ports that you want to use into. Being based in Switzerland is great, as it is one of the best countries for online privacy. I can't find many user reviews about Exoscale, but CERN uses it. Exoscale embraces open source software and at the moment they have 217 repositories on GitHub.
There's a nice, detailed guide for setting up a website with nginx and Let's Encrypt on Exoscale here. The data centers Exoscale rents are located in Geneva, Switzerland; Frankfurt, Germany; and Vienna, Austria.
I am currently using Exoscale for a school project and it has been great so far. The support staff answered within an hour when I submitted a support ticket early in the morning.
I do, however, have some criticism. The payment options are credit/debit card and PayPal, but recurring payments via PayPal has not been enabled as a payment option, so unless you want to store your credit/debit card info with Exoscale's payment processor PostFinance so that Exoscale can automatically charge your credit/debit card, you're going to have to manually add funds to your account. This is a problem because Exoscale doesn't notify you before your account runs out of money. Instead, they send an email when your account is out of money and your VPS has been powered down. They give you 29 days to pay the bill before the VPS is deleted, so your data remains intact, at least. Something else that annoys me is that their prices don't include taxes, so a 5€ VPS costs 6,20€ in reality, for example.
That said, I'm still a happy paying customer and I'd recommend Exoscale over other fancy DevOps cloud hosting platforms like DigitalOcean (which I tried two years ago) in a heartbeat. The biggest con is that Exoscale is slightly more expensive and offers less of a bang for the buck specs-wise than a lot of their bigger competitors, but if you just need a small VPS for a low traffic site, they're a solid choice.
There's also a similar Swiss VPS hosting company called cloudscale.ch, but they are a lot more expensive than Exoscale without offering anything that Exoscale does not already provide, as far as I can see.
Cloudscale.ch also runs analytics in the form of a Matomo instance, which is as privacy friendly as you can get with analytics since Matomo is self-hosted and open source. However, as far as I can see, Exoscale don't use any analytics at all, which is even better.
