Stayed in a few places recently. I'll only include the hotels rather than Airbnbs and sleeper train seats.
Ibis Bidget Caen Gare (France)
Did the job. Quite a tired room, but perfectly acceptable. Friendly receptionist on arrival who spoke excellent English. A bit out of town, but directly opposite the station which was the sole reason I booked it. Bed was the usual Ibis Budget very firm bed, but after a poor night's sleep on a very rough ferry crossing the previous night, I'd have probably had no trouble sleeping on the platform! Slept very well and perfectly set up for an early train the next day.
OBB Nightjet Mini Cabin
Had an upper level cabin, a huge upgrade over a regular couchette as it is properly private. However the window is tiny, so forget about seeing outside. Slept pretty well, but they do take all the bedding off you about 90 minutes before arrival, so bear that in mind if you want a lie in. Went down to the seats for a couple of hours in the evening as the cabin bed was quite uncomfortable to sit up on for a long time. The supplement (€75) seemed quite expensive too, given I paid €90 for a proper cabin supplement in Norway a few months back.
B&B Hotels, Katowice (Poland)
First time I've stayed at the B&B Hotels chain, and I'm returning to this hotel this weekend. About 5 minutes from the station which was perfect. Spacious room with air con and very comfy. Not too dissimilar from an older Premier Inn really. No bar, but a fridge with a good selection of drinks and snacks, and breakfast was available. Unfortunately the second "night" I stayed, my train back from Warsaw had a fatality and I only got back at 7AM, 8 hours late. Thankfully check out as standard is 12PM. Which I was very greatful for. Apparently if you join their loyalty scheme, you get a late check out (2PM!) if you check out on a Sunday free of charge.
Guesthouse Outa, Rovaniemi (Finland)
Very impressed with this one. €50 for the night in that part of the world seemed a steal, though i imagine it gets significantly more expensive at Christmas time. Right in the heart of the town centre, yet very peaceful and comfortable. Would definitely stay again.
Victoria 1, Tallink Ferry
This seemed like an absolute steal. for the convenience and novelty factor I just couldn't resist. The ship sails to Tallinn and moors up for the night. Yet you can pay an extra €40 (or indeed more if you want a better cabin) and get a cabin for the night. I figured I'd probably be exhausted after a poor night's sleep on the train the previous night, which I was, so didn't really want the hassle of having to drag my stuff off the ship at 22:30 and find a similar if not higher priced hotel. This paid off as I fell asleep while we were still sailing, but then got woke up by the disembarkation announcement. So back to the bar I went, oh dear!

It was a nice cabin given it was the cheapest one, but it was a strange experience sleeping on a ship in literal silence. Not a single vibration, rumble of the engine or motion.
Lollo Apartments, Vilnius (Lithuania)
I was a bit nervous about this one. Some of the reviews are pretty poor. But I needn't have worried. First impression was pretty poor, it's basically a building site when you first enter the building. But once you're in it's actually pretty good. Decent size room with a private bathroom, plenty of plugs and spotlessly clean. And a good craft beer bar round the corner too.
