The staff were friendly and explained what I needed to know.
The instructions for check-in were confusing however, because I thought I had to call before arriving. Turns out that I just needed to go specified address and contact Johan to go through the check-in process.
The shower was a little lukewarm, but wasn't too much of a problem after turning up the room and bathroom radiators.
Also be ready to pay 10EUR per night tax (Belgium thing), as well as a 100EUR deposit (which will be returned during check-out and inspection).
Nearest transport is the 82 Tram line (stop is Van Zande), and to get to Brussels centre you can stop at west station or Brussels Midi (south) and change to the metro lines. You can find the pdf map files on the STIB-MIVB website (if you used the London underground maps before, shouldn't be too difficult). Also, you can the MoBIB card (like the London Oyster card) from the ticket machines themselves which is something that took me a few days to figure out (5EUR fee for new card).
Thanks to J and R!
