You might try- the Goldbelt Hotel- http://www.goldbelttours.com/travel/lodging/hotel.html

they have wireless internet- but all internet can be problematic here- just learn to live with it- part of being in "the last frontier"-

Have not been in rooms for many years- can not tell you the quality there-

It is within walking distance to all downtown Juneau areas- and if you get a front of building room should have nice views of the channel.
