Cove Centrum is right in the Center of Den Haag. The room looked really nice and everything was clean.
Only flaw are the lights - a ceiling light in the main room is missing, so it's quite dark in the evening. Also nice to know is that the bath with the shower and tub doesn't has a door (toilet is in an extra room tho).
Check-in and out was easy and quick. Everybody was really nice. All in all I can recommend Cove Centrum.
