"Clean, comfortable room. Friendly staff. Garage parking is secure. Extra large vehicles will struggle. Hallways are narrow and especially so when the housekeepers are at work because their carts take up a lot of room. Easy enough to deal with but tight for anyone with a walker.

The Belltown Inn

10/10 Excellent
"Had an amazing time staying at the Belltown in!! We got escorted from the airport by their luxury car service which had amazing service and a luxury pickup car at an affordable price (small business too!). It was a clean property with suitable amenities like town recommendations, morning coffee, small kitchenette in rooms and free toiletries. Our room was organized every day and staff were so friendly. Itโ€™s unfortunate how many homeless linger around the properties streets because the area is otherwise very cute and pedestrian friendly, but staff made us feel safe by locking doors at 10 pm (with card access), 24 hour staff, and security at the front during morning or late hours. I loved how close it was to everything, I was in town for only a short time and was still able to explore all of the Seattle attractions by walking, no need for a car! Theyโ€™re also right next door to biscuit B** which is an amazing and popular breakfast place with amazing (not surprisingly) biscuits!"
