The workshop venue, apart from conference halls and nice coffee and lunch breaks, offers accommodation as well. It offers 73 reasonably-priced single, double and triple rooms. They can be booked here or via booking.com. However, since the venue is located directly in the city center, there are plenty of other options in walking distance:
Erbacher Hof (Workshop Venue)
Intercity Hotel Mainz
Holiday Inn -the niu, Mood Mainz
