The what I enjoyed was that it was close to the exhibition I visited - Didacta 2018 was literally a few steps away.
The hotel was not dirty but wasn’t clean either. The staff wasn’t unfriendly but wasn’t really friendly either - one guy could not put even a little smile on.
The bar wasn’t open, but the staff were ready to serve a tea or coffee after asking.
The center is far, at least a 20-30 minute ride by tram.
