It’s all right and you get what you pay for. The beds are like 5 cm thick’s and somewhat uncomfortable. There’s no sound-proofing what so ever, so you hear when people arrive/leave and when they open and close their doors to the shuttle, so the amount of peaceful sleep you get is quite low.
That being said it’s like 30 euros a night, and very clean and easy to check in and out so it does job if you want something easy and cheap.
