Julian's apartment is amazing. Wonderful views on all sides (even the bathroom!). We had great weather so were lucky enough to sunbathe and eat and drink out on the balconies (there are 3!).
The amenities are great too (coffee machine, washing machine , automatic vacuum cleaner' Netflix). And it's just a really cool and very large space to hang out.
The metro is literally right outside the door and it's just 2 stops to midi train station (or a short walk). There's a lovely children's playground right outside the flat and grocery shops very close (the bigger ones were closed on sun). It takes about 15 to 20 mins to walk to grand place via sablon so ideally located for sight seeing.
Julian and his flatmate were extremely helpful, offering tips on where to eat and drink etc. Julian even came immediately to rescue is one morning when we locked ourselves in (don't lock the deadlocks from inside the flat!).
There's so much to see and do in Brussels for all ages. The grand place beautiful and all lit up at night. We loved mini Europe and the musical instrument museum. There is also wonderful food and obviously beer (we loved the chips, mussels, waffles and chocolates). We also took the train to Bruges which is about an hour away and very beautiful (something we didn't realize is that if you travel to Brussels by Eurostar you can use your ticket to go to any city in Belgium for 24 hours after you arrive or to return 24 hours before you take the Eurostar back so one leg of your journey is free).
Brussels is quite big and busy though so it was great to be able to retreat to the apartment where we could get away from it all and simply sit and watch the world go by. There were some street acrobats that came every day and did a routine for traffic while they waited at the red light that my daughter's (8 + 11) loved watching. All in all we couldn't have asked for a better visit.
