Lodging

Good option is Hotel "Club 1943" (http://www.hotelclub1934.lv/?lang=US), they offer rooms for 36 Eur per night for two people (18 Eur per person) + 8 eur per person if you want breakfast too.

 

If you decide to stay there then make accomodations as soon as possible, because they dont have enough rooms for all participants.
