Enjoyed my stay at the Cove Centrum. It's right at Grote Markt, so very central, but still very quiet in the rooms and on the corridors for undisturbed work and sleep. The studio was modern, clean and stylish, and so was the co-working space in the reception area.
My only point of criticism would be related to communication: even though I indicated my arrival time in advance as very late and 24/7 reception is available, I received a message my reservation would go as a no-show. This was a bit confusing, however, after I re-confirmed my arrival time everything was fine.
Overall, I can recommend staying here and would stay again :)
