The apartment has an excellent location. It is next to the Bourse de Bruxelles.
The communication is perfect since it has next to a subway stop that communicates directly with the Brussels-Nord train station, from which you can get to the airport, Bruges, Ghent, Antwerp... The Brussels-Central train station is only a 10-minute walk away.
The only thing you can put on it is that it is the third floor without a lift. But the location makes up for it.
As for Dat, I can only say good things. Communication with him has been excellent and he's helped us in every way. As a host 10 points!
I would certainly repeat :)
