Hotel Steigenberger a Bruxelles

The room size was OK. I was in a Deluxe room on the 2nd floor with balcony and view to the inner courtyard. I had specifically asked for a quiet room on a higher floor (arrival was on a Friday, stayed until Sunday). During both nights there were festivities going on in the hotel (first a bachelor party and the next night the wedding). The noise (music, etc.) in the evening and during the night was unacceptable for such a high standard hotel. Even when the windows were closed, the noise was clearly audible. Around midnight I went to the reception to complain - both nights. I was told that this event would go on until at least 3 a.m. I was offered to move to another room - but I did not accept that, since I expected to be disturbed by the noise in most rooms. I was told that at my check-out a manager would be available to take in person my complaint - which, of course did not happen. On Saturday after lunch I wanted to have coffee/cake with a friend in the hotel restaurant/terrace. It took the waiter almost 20 minutes to come and take our order. When arriving at our table, he just told us that there is a QR code which we need to scan in to see the menu. We did not place an order and left - very disappointing experience! Another issue was that I was travelling alone and was put in a room with connecting doors, which I believe is not suitable for solo travellers, esp. for females. I informed the hotel about all the above and received only very poor replies. The noise situation has to be improved - if a hotel does not have suitable rooms for parties, then don't rent them out when you have paying guests who at least want to sleep at midnight.
