My boyfriend and I stayed in Bruxelles for 5 nights and Coco's apartment was absolutely lovely! Very cozy and with a perfect location.
It's very easy to get there from Brussels Midi Station and, unless you need to go to the other side of the city, you can easily walk everywhere.
Despite being on a very lively street, the area is very quiet at night so you will be able to rest and sleep through the night.
The apartment is very well equipped and it's got everything you might need during your stay. The hosts are absolutely lovely and always happy to help or answer any questions.
Absolutely recommended!
