Heidelberg is a very popular tourist destination, soon you will know why 🙂
One drawback is that the city is running out of hotel and hostel places soon and you might not find an accommodation that would suit all your requirements.
We suggest you to book your accommodation early.
Here is a map with the venue and many hotels and hostels mapped out:

Please write to firstname.lastname@example.org if you would like help with getting hosted. However, hosting spots are often tight in Heidelberg, and we are still collecting participants who are willing and able to host. That means, we can probably only start pairing up your request with a host as of April 2016. We recommend that you take initiative by contacting your dancing friends directly / via Facebook and/or check out hostel options as well.
