We stayed in the appartment with 11 guests and all of them absolutely loved it. It's location is fantastic, right in the middle of the old city centre. So all major attractions are easily within walking distance. The appartment was clean and very well equipped and Benoit was very helpful by letting us stay a little bit longer and helping us with all our questions. He stocked the frigde full of beverages, which was very convenient. I would absolutely recommend staying here, especially if you're looking for a nice place to stay in Brussels with a group.
