Road construction
As others have mentioned this hotel is pretty great and I agree. It does the job and is perhaps one of the nicest options in Antwerp.
With that said when I was staying it was pretty empty. I wonder if noise can be a problem if it’s busy as the place seems to be a collection of very old buildings.
The most glaring issue though as of now is no fault to the hotel - the entire road in front of the hotel has been torn up and construction is ongoing. I’m honestly not sure how any cars can get to the hotel at this moment, and in addition you might have noise issues if your room faces the road.
I arrived via train + metro with little luggage and was also placed in a room facing a courtyard, so the construction was no issue to me. But perhaps it might be for others.
