Overall, we enjoyed our time in Brussels... the location is great. Just an fyi, only one of the heaters appears to be functional, which took us a bit to figure out. The apartment was warm enough with just the one heater once we realized that there was one that worked. However, it was a very cold first night when we thought all of them were broken. The interior of building itself is not the nicest (and is above a cannabis shop), but the actual apartment is good. We arrived after regular check in hours and were able to figure out how to get the keys pretty easily. Unfortunately, because we arrived after their check in hours, we were instructed to meet at their office (this is run by a company, not an individual) to complete the check in procedure the following day between 10am-12pm. When we arrived at 10:30, there was nobody there. We checked back at the office at 11, and again nobody was there. A bit later we received a message that they were at the office and that we could come back. It was unfortunate to waste our only morning in Brussels returning to the office three times when we could have been exploring the city.
