    Review Summary for 21 Montrose Avenue
    Summarized from anonymous rental reviews on openigloo.
    Recent reviews of 21 Montrose Avenue praise its clean environment, rooftop, gym, and generally quiet tenants. Many appreciate the responsive management and noted amenities like an elevator. However, multiple renters highlight issues with heating efficiency and poor window insulation causing cold drafts and condensation problems. Some mention inconsistent maintenance quality, such as temporary fixes leading to recurring issues. Garbage management and pest control receive mixed feedback, with occasional dissatisfaction. Noise levels and neighbor interactions are mostly positive. Renters advise improvements in HVAC systems, window sealing, and more proactive owner responsiveness to enhance living comfort. Overall, the building offers good amenities but needs attention to maintenance and heating.

    Former Tenant
    Pros:
    Management was alright, fairly responsive

    We had a leaky sink and they used cheap materials to fix it so immediately leaked again. It was fixed the second time around but still annoying.
