Last month I travelled from Kyiv to Brussels by bus because flying with a lot of luggage was too complicated and expensive. I used which someone in a Facebook group recommended. I contacted them via Viber, got the schedule and details quickly, and booked a seat. The bus was clean, comfortable, and had working air conditioning, USB ports, and even Wi-Fi, which helped a lot during the long ride. They picked me up near the central station, helped with my two heavy suitcases, and gave clear info before we reached the EU border. Border control was smooth – they just checked passports and asked a few questions. I didn’t need to declare anything because all I had was personal stuff. We arrived in Brussels the next day without delays. I’d definitely recommend this if you're looking for a cheaper and well-organized way to get to Belgium.
