Island Square offers a prime Mercer Island location with walkable access to shops, restaurants, and transit, plus well-maintained renovated units and strong on-site management. Most residents praise the responsive staff and community atmosphere, though some experience disruptions from ongoing construction, occasional elevator maintenance issues, and noise from street-facing units or neighboring residents. Fees and billing practices have been a concern for a small number of residents.
Management and office staff are consistently praised for being responsive, friendly, and professional, with many residents highlighting their helpfulness and approachability. However, some residents experienced issues during the leasing and move-in process, including miscommunications about amenities and unfulfilled promises, as well as concerns about billing communication and late fee policies. The property management team is generally well-regarded for their day-to-day service, though process improvements in the leasing phase and communication transparency could enhance the resident experience.
Island Square offers a highly walkable location on Mercer Island with convenient access to grocery stores, restaurants, and parks within walking distance, plus quick freeway access to Seattle and Bellevue for commuters. Street parking is available nearby, though some residents note limited reasonably priced parking options. The property's location is consistently praised as a major strength, though residents should be aware of ongoing construction projects and occasional maintenance disruptions.
Island Square offers well-maintained amenities including a modern gym with sauna, clean common spaces, and a convenient central location near grocery stores and transit. However, residents report ongoing challenges with elevator maintenance, package delivery accuracy, parking garage congestion, and extended construction projects that were not pre-disclosed. Amenity completion timelines—particularly the hot tub—have extended beyond resident expectations.
Residents report significant noise issues stemming from hardwood floor installations, ongoing construction projects, and inadequate sound insulation between units. Elevator reliability is a major concern, with multiple extended outages and at least one incident requiring fire department rescue. Building cleanliness and maintenance responsiveness vary; while some residents praise upkeep and renovations, others note dirty stairwells, hallway litter, and delayed repairs. Management communication about planned construction and service disruptions has been inconsistent.
Maintenance staff are consistently praised for responsiveness and punctuality in addressing repair requests. Most residents report positive experiences with work order completion, though some note ongoing issues with amenity maintenance (hot tub renovation) and occasional water service interruptions. Elevator breakdowns have been reported as a recurring concern.
