Very convenient for long-term connections. I can't say that it's cheap, but sleep is more important)
we stayed several times, if you don't book online in advance, it often happens that all the seats are occupied.
We took rooms with two beds, one above the other. Everything is clean. The toilet is shared, but it is regularly cleaned, it does not cause disgust.
You can pour coffee for free near the reception.
The wand is a lifesaver. We took 3 hours of sleep and the whole family, like the dead, were recuperating after a difficult flight.
We recommend that you keep an eye on the vacationers, they slammed doors and talked loudly when we were there, which interfered with sleep.
Before selling seats at the hotel, you should have been notified that you cannot come to you without a boarding pass and you should also have a flight from Terminal 1, but not from another terminal. I bought a room for 114€, but I was not allowed to check in. They just wouldn't let me in without a boarding pass. I just arrived, I wanted to sleep and I have to fly tomorrow.
