My girlfriend and I spend 4 days in the Grand Mark and there is not much to not love about that place. The Suite was really roomy, huge shower & bathtub, nicely climatized, handy cooking corner, ... Service was great, everyone was so nice to us!
Our car was parked in a garage nearby, we had to hand in the keys to the service and they took car of it, really convenient, parking was about 20€/night) but even much more if you just parked outside using the parking machine (if you even found a space..) so it was a good opportunity.
Breakfast was good, everything you expect, not more, but not less and you got to enjoy the view of the beautiful garden while eating or even sit outside when the weather allows it :)
the location is perfect for holiday trips, you can reach public transport and almost anything there is to visit in the old town by feet, there is a good supermarket and a mall around the corner, several restaurants anda access to many shoppings miles nearby. perfect.
things to consider:
the first shower on the other hand led to a quite bad smell coming from the drain (Room 316) (you might want to look into it) - but it was NOT noticable after that.
9.5/10
I would come again!
