I have lived at the Sidney since March 2014 and I absolutely LOVE it. The property manager Sara and her team are amazing and they go above and beyond to accommodate the residents. Unlike many of the new buildings in Belltown, the Sidney does not have a corporate feel, in fact when I first moved in I thought it was self-managed because it felt so "homey" and the staff genuinely care about the building and residents. I have lived in other buildings where the property management company was such a nightmare and this is completely the opposite at the Sidney. The property is very well maintained, clean, and has modern furnishings. The few occasions that I had a maintenance request, it was fixed the same day!
Location: The location is great because there is always plenty of street parking for visitors, it's quite at night, yet only two blocks away for the Belltown nightlife.
Noise: I have never had any issues with noise, in fact I have never even heard my neighbors.
Parking: plenty of parking spots in the garage and never any vandalism or theft (I often leave my car unlocked and have never had issues).
Other residents: everyone (including their dogs) that I have met in the building have been extremely friendly.
