The apartment is just AMAZING!! I am so glad we got to experience this place. It did not feel like we were tourists but like we were locals. The parking spot is a big plus. Brussels is a HUGE and busy city. This location was ideal to go to the Atrium and Mini-Europe by car. The apartment is big, ideal for a big group, family reunion,... 4 nice bedrooms: 1 big bedroom on one side with a bathroom, and 3 other bedrooms on the other side: 1 big bedroom with a bathroom and 2 regular size bedrooms.
However...
The mansion is right on a rather busy street with quite a lot of trucks. We could feel the house trembling from time to time and the noise could be pretty loud (but also because we had to let the windows open because of the heat... we stayed there during the heat wave this summer and the apartment is under the roof with no AC).
Not the best of neighborhood... we never felt unsafe even when we were coming back at night after a long day in the city but we were a group. It would take us about 40 minutes to go downtown. There was no bakery close by we could walk to to get some breakfast / bread so we had to go to the supermarket close by. Not a big deal but well, again, it made us feel like we were in the suburb.
