Hot and noisy
We just completed an overnight stay at Belltown Inn. The location is great and the price is good but there are some significant negatives as well. 
We were in a corner room which was exceptionally loud with street noise, especially the repeated emergency vehicles that leave from the station which is around the corner. But if you shut the windows the room is an oven because there is no air-conditioning.
Also the mattresses are uncomfortable. 
Parking also an issue because there isn't any. you have to find street parking or use a lot that about 1.5 blocks away. 
The overnight front desk staff were unhelpful and suggested that we were in fact in a good room that "people pay an extra $75 for ususally". Hummm. However the morning staff were very nice and even went out of their way to find a balloon for my toddler.
