We cut our 2-night stay short because there was no hot water. We found out there was no hot water shortly before check-in but opted to stay anyways because we had just arrived after a full day of travel and the plumber was scheduled for 8am the next morning. Unfortunately, the water could not be repaired. We ended up staying at a hotel nearby.
Overall, the value for the studio is good if the hot water is working. The location is great- close to the train station, Grande Place, many shops and restaurants. We stayed at a hotel nearby the 2nd night that was equally walkable, and much more quiet. If you are bothered by street noise in the morning, I would recommend hotel La Legend . The noise was not as bad as we thought it would be based on other reviews. At night, we didn't find it too bad but it's certainly a busy street in the morning. Worth the stay if you are spending time in Brussels. I see an old review that mentioned issue with the hot water as well, something to keep in mind.
