Hammarby Fabriksväg in Stockholm. It is just south of Skanstull.

But my guess is that you will need to pay a fair bit more for your hosting if you need 24/7 physical access to the server.

A hardware remote control possibility like mentioned above is a good investment though. You can reinstall your server from scratch, access bios settings, do basic trouble shooting and so on, without physical access.
