This is no hotel nor a hostel, it's like a storage facility, like you see in the movies that was added a bed and shower.
There are no windows in the room, and the door is a see through sliding door with a rolling mechanical curtain, like you have in offices.
I didn't feel comfortable at this place at all, even for just one night, and at over 50€ per night, it is completly overpriced.
No staff even works there, you get the key yourself from a box, and put it in another when you leave.
Do youself a favour and go to a real hotel, or to a hostel if you prefer, but pay much less than i did.
