Wonderful value for money and Christophe is a very friendly and accommodating host. He knows Brussels really well and is always happy to give suggestions.
I liked Schaerbeek as an area - multicultural and down-to-earth. It's pretty quiet, feels safe, and many attractions in the city centre can be reached in a 30-minute walk or so.
Warning: there are quite a few stairs to get to the room. It's at the top of the house, so 3 short flights away from the bathroom and 6 away from the ground floor with the kitchen.
There's more shelving in the room than shown in the picture. I stayed during a heat wave and it did get very warm... but then so did everywhere else in Belgium. The top window can open very wide and there was a fan available; these of course helped.
In the kitchen, each room gets a separate space for pantry stuff, and there's a shared "please use" box. The place is well stocked, including plenty of tupperware available.
The washing machine and dryer are new and high quality, with good laundry detergent available to use.
Internet connection was fantastic throughout. Could even connect well enough in the garden, which was also a wonderful space. Loads of fresh grapes ^_^
All in all, even with 5 other rooms occupied, there always felt like there was plenty of space in the house.
