Hotel

Directly next to the convention center there's a NH Hotel.
To book a room it's best to contact them directly.

The hotel address is:

NH hotel Maastricht
Forum 110
6229 GV Maastricht
www.nh-hotels.com

About 300 meter further there's another hotel.

Apart Hotel Randwyck
Endepolsdomein 30
6229 EM Maastricht

Ofcourse you can always go to booking.com to look for other options.

!!! Hotel reservation warning:

We will NEVER phone you regarding your own hotel reservation.

Scam hotel reservation companies may possibly try to contact you
– representing themselves with a name which will give you the impression
that they are connected to us and then offer you to book a room for you.

Do NOT do business with them!
They are not cheap and they may book a hotel for you which is far from
the convention. And sometimes without the option to cancel.
DO NOT BOOK THROUGH THEM!!!
