The apartment is perfectly located, close to the old town and the railway station. We did not use public transport in Brussel at all, visited all the attractions by foot. Quite courtyard is wonderful addition.
You only need to be careful with window and door locks, they're a bit old and it might take time and accuracy to open or close them. And a little creaky bed :)
Jeremie left products for breakfast in the apartment, it was great.
Jeremie answered all my questions quickly and in detail. Communication was very pleasant.
