Yeah, a 22:00 arrival is tricky. And on a Friday night.
Have you thought about AirBnB?
Or check the likes of Booking.com - sometimes they have deals close (or the day before) the date. After a day's work it may be worth the expense?
Failing that, Warmshowers (sign up fee required if not already a member) may be of help or a local scouting organisation even.
Anything to be said for a half day at work?
