A very special place indeed! I believe it is (or was) an artists' retreat, above the changing rooms of the theater. A truly incredible space, with amazing furnishings and original touches. The largest bed we've ever seen (close to 180cm) and the biggest shower (the elevator of the Belfry, meant to hold 10 people, is smaller!), not forgetting the bathtub and double sinks! We didn't have a chance to use the terrace but it's just as crazy as the rest. The mini fridge was also much appreciated given the hot weather we had. Oh and the breakfast (extra) is fit for a King!
The surrounding area is slightly edgy, but as promised barely 15 minutes' walk to the very center. Seems quiet but the rooms don't overlook the street anyway, so nice and calm. We managed to find parking spaces in the surrounding streets every time we needed to, but sometimes it felt like we were a bit lucky (although things are undoubtedly better since the Low Emission Zone was instituted, as this area is just inside it) (watch out for Dampoortstraat, which is a hybrid orange-red in an otherwise orange tariff zone, so you can't park daily on it).
But nevermind all that, it was an amazing experience and we will be sure to head straight back to the Theater Box on our next visit!
