Umeå is good choice IMO, relatively big city with good transportation connections (train, airplane and by road as well as a ferry to Vasa in Finland) and should be able to offer
a fairly good amount of hotel rooms. The area around Vännäs west of Umeå have hosted many successful rounds in the Swedish rally championship.
The disadvantage is the distance from South East Norway with the Oslo-Hamar region.

Two stages with Ekström from last year's SM-round in Umeå. Some of them will surely be used in next year's WRC round.
