Booked the room for 6 for our family of 5. Brilliant options, with 4 full single bunks as you go in (all with their own usb ports, socket and lights) and then a good size double through a pocket door.
Shout out to Elvis who enthusiastically greeted our kids every time we came in or out.
Easy walk to the center or Eurostar, although public transport/Uber also available....
