Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback for buildings managed by GUARDEUM MANAGEMENT reveals a mixed experience with significant variability across properties. While some tenants praise responsiveness, prompt maintenance, and convenient locations—especially at 471 Keap Street—others report serious issues such as poor communication, delayed security deposit returns, and disputes over rent and fees. Cleanliness and pest control standards appear inconsistent, with some units suffering from mold, rodent problems, and overall neglect. Noise levels and neighbor quality vary, with some buildings plagued by loud environments and disrespectful management. Overall, expect management to be responsive in select buildings but prepare for potential challenges related to maintenance, transparency, and tenant relations.

DO NOT LIVE HERE - Fine Building but Horrible Management

Pros

It was a fine place to live. Overpriced and poorly built and maintained, but fine.

Cons

The Landlord, Martin, has not returned our security deposit after 3 months. We left the apartment in great condition and did not receive any notice from the landlord about damages. We have been attempting to contact Martin and Guardeum Management for months, with no success. We are owed over $8000, so we have hired a lawyer and will be taking them to small claims court.

I’ll miss 471 Keap!

Pros

Landlord very responsive to things like light bill replacement, toilet broken, broken dishwasher, etc. Best location ever. Can’t beat it. Bike rack is great
