"Bed booked not available, AC defevtive"

Bed booked not available. Categorie other than booked. Climate was not working, very high temperatures in the cabin. Toilets not functional.

"Convenient way to travel"

Convenient way to travel. Train is old, sound could not be adjusted if you didn’t want to hear the announcements. Fire alarms were too sensitive where the stewards didn’t want you to use spray deodorants. Toilets by the morning were out of paper and filthy

"Nooit meer !"

Nooit meer !

""The images shown may differ from reality""

Spoiler from European Sleeper: "The images shown may differ from reality" (note this remark under the travel options images on their website).
Unfortunately, it was disappointing. I had hoped for a good, sustainable alternative to flying when traveling to Germany and the Czech Republic, but I doubt I would use it again. Despite a seat in a 6-person compartment being more expensive than a plane ticket combined with a train ticket to the airport, we encountered several issues. For this price, we had one non-working toilet in our train car, and the other toilet had a broken lock, so the door couldn’t be closed. Additionally, the lights weren’t working properly, and we arrived almost two hours late at our final destination. I hope they improve the passenger experience or adjust the price, so this can become a competitive alternative to flying.

"Comfortable"

Comfortable, clean, on time and friendly staff

"Experience always good, but too pricy"

I always find the experience good. I'm just thinking it is very expensive overall for a night train that is quite old. I believe tickets for such route should be around 80€ max and not above 100€ for a 5-person compartment (early days were 4-persons. Now there's barely any difference as it's 6 or 5 persons).

"I recently took the EuroSleeper from…"

I recently took the EuroSleeper from Amsterdam to Berlin, and I had a great experience. I stayed in a 5-person compartment exclusively for women and had the middle bed. Everything was smooth—the train was on time, and the facilities were as clean as you could expect on an overnight train. It felt safe, comfortable, and well-organized. I would definitely travel with EuroSleeper again and highly recommend it to others looking for a relaxing and hassle-free way to travel between cities.

"Good alternative to flying"

All in all a good experience, cabin was a little smaller than expected, especially considering there was no general coach to hang out in

"suggestions for improvements "

The problem remains the old rolling stock.
You cannot do anything about this structurally, but:
please make sure that every facility that exists is really working (e.g. each upstairs bed has a reling), the ladder works, the lights work, the windows can be opened rather easily than with force only.
And above all:
1. do all you can to improve the sanitary situation. Each toilet and bathrom needs to be cleaned hourly or so. Provide small really towels, use scent, improve the lights...
2. provide "some" seating areas for those who go to bed later than the rest of the group.

"on time"

on time - this was great
but quite few space...
