Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews for buildings managed by 21ST OWNER LLC reveal a mixed experience. Positive feedback highlights responsive onsite supers, well-maintained and clean properties, and safe, friendly neighborhoods with modern renovations and quiet environments. However, some buildings struggle with pest control, especially rodent infestations, and tenants report slow or neglectful management responses, particularly regarding maintenance requests and communication. Garbage management is generally good, but a few locations face sanitation issues. Rent hikes and lack of laundry facilities are concerns for some. Overall, expect responsive supers and decent upkeep in select buildings, but also be prepared for occasional management delays and pest-related challenges.
