The place is situated in an amazing part of town. Seriously, you could not ask to be closer to the town square AND Delirium Bar. It’s also only about 10 mins to the museums and 20 mins walk/10 min train ride to Cantillon (which you should do).
The only thing I would caution is the noise from the train that runs most of the night. If you are a light sleeper, it may wake you up. But hey! It’s part of being downtown. Would definitely stay again.
