Good location very close to the train station and the city centre is also within walking distance. The staff were also very friendly and helpful.
Otherwise the impression was rather so-so; definitely not 4 star hotel; apart from the very well equipped gym and the pool, it is more of a youth hostel deluxe.
For example, there is no kettle or a coffee preparation in the room. There is only a reading light on one side of the double bed, air conditioning and the (rather uncomfortable) room light cannot be switched from the bed, only directly on a switch on the door.
The room itself was very clean - but the black and eternally long corridors were much less so.
Also not nice: if you're unlucky like us, it's a room with a (large) window that only looks into a narrow light well. Opposite, 4 metres away, there is a view into another room. The only thing left to do for privacy was to draw the pitch-black curtains.
And the fact that you have to enter all your details yourself when checking in is not so much "easy" and more "easyJet".
Conclusion: at a favourable price okay for a short stay, but nothing more.
