I have stayed at the Thon several times before, whenever I visit family in Brussels, and have always given glowing reviews and have been very satisfied with my stays. I had booked this stay some while ago as a pay at the property deal as I usually do. I arrived at the hotel just before 21:00 after a family dinner. I was astonished to be told that the hotel was overbooked and no rooms were available due to the school holidays. I was offered an apartment in the Residence Stephanie which I had no option but to accept. I was offered a free breakfast as some compensation. The Residence is a block and a half from the hotel, but fortunately it wasn't raining. The apartment was adequately sized with all the facilities you would expect in a serviced apartment, however none of these were actually of use to me as I was only staying one night. The bed was comfortable but due to the layout of the apartment there were no bedside tables, nor were there reading lights that could be turned out from the bed. I also found the apartment quite noisy with a lot of street noise, despite it not facing directly onto Avenue Louise, The bathroom and shower were clean and very good. I returned to the Hotel in the morning for breakfast and complained to the check in staff about being moved and the noisy apartment, however all I got was a promise that the next time would be a better experience. The breakfast was, as always, excellent with a great choice of cold and hot food.
