This is a nice place to stay. You got everything yiu need. Every little detail is thought.
There are some nice restaurants in walking distance as well as big and small markets. Center of Jette is just 5 minutes walk.
A little far to everything but with tram and bus and metro you can reach anywhere easily. Bus stop for 88 is 10m far and tram stop for 51 is 100m far. If you wanna walk to the old city center this is not your place but to experience the real Brussels and a silent district that people lives; great location.
10 minutes tram ride to the expo district. (Atomium, Mini Europe, Adam etc)
If I come back to Brussels again I guess I would like to stay there again.
