Flori's place is great for two or even three people. It is very close to the downtown which allows you to walk to almost all of the major sites. The check in process was seamless and took only a few minutes.
The apartment was spotless with all the necessary amenities you may need. The TV was equipped with Netflix which was great. The bed in the bedroom was very cozy and the room had thick curtains so likely you wouldn't be awoken by the light. I don't think I'd recommend the couch in the living room for sleeping but it was perfectly fine for lounging. The bathroom appeared brand new with a large glass shower and excellent water pressure. There is also a dual washer/dryer which came in handy after an extended trip.
All in all, I highly recommend Flori's place for a short trip to Brussels!
