Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews of buildings managed by Jon Diacomanolis reveal a mixed management reputation. While some properties benefit from good location and neighborly communities with responsive management, others suffer from significant issues including poor cleanliness, ineffective garbage management, pest infestations, inconsistent hot water, and unresponsive maintenance. Several tenants report problems such as sewage leaks, noise disturbances, and weak water pressure. Parking and building upkeep have also been noted as areas needing improvement. Prospective renters should expect variability depending on the specific building, with some well-maintained properties alongside others that require major management attention and upgrades.

I found a mouse and I suspect there were several mice

Pros

Good location and cheap

I had a mouse in my apartment and they kept coming back to eat the poison for a couple of months. Parking also not great. Hot water is not consistent in the shower.
