My gf and I stayed at Kike's place for a long weekend which was perfect for Brussels. We explored for about a day and a half and then took the train to Brugge another day (which I would highly recommend). Everything is close to his apartment. If you have trouble with stairs, than this is not the place for you, but if you don't mind 4 flights, then this is a great place to stay. Communication with Kike was easy, and he provided us with full details about how to check-in/check-out. I would definitely stay here again if we came back.
