The house is amazingly clean and full of cute stylish details.
The neighborhood is safe and residencial, a little away from the center, but you have 2 options of metro/train just near by. As Bruxelles is small to medium size town you can do what you want easily and fast with the public transports.
The room is small but super comfy and sparkling clean, with wardrobes and tools to organize your stuff. Perfect for 1 and fair enough for a couple.
If you're a light sleeper it can be difficult as the walls are thin, you can listen a lot of what's going on upstairs. The lack of natural light inside the room is also something I want to remark. We had problems to access the bathroom to shower at a time. I think it could be solved with more communication between the hostess and us, but for quick necessities you have a spare and private toilet.
I had a nice time in Bruxelles during the New Years and the accommodation helped the good impression.
I couldn't talk much with Marie because she was traveling half of our stay, but she seems very open and energetic.
An elegant surrounding for an elegant city!
