-they're quite nice
-the space is kinda limited, noticeable when you need to transfer a backpack or something from one end to the other of it
-the lower ones definitely felt better
-the sleeping surface was actually good (!!!) still on the hard side, but they had actual padding. definitely better than the comfort couchettes.
-no individualized thermostat, I feel that's a big loss from the normal couchettes. and I was a biiiit cold during the night (so I stole the blanket from the empty cabin next to mine)
-the luggage space is a bit less convenient, but good enough. you leave it in a separate carriage with a dedicated spot with locks, which is not a big deal, but it's inconvenient to go there from your minicabin when boarding, probably better to just go there directly. the lower ones have extra storage space below the mattress too.
