Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews of buildings managed by John MacGowan reveal a mixed management experience. While the building staff, especially front desk and maintenance teams, consistently receive high praise for their friendliness and helpfulness, the owner’s responsiveness is frequently criticized as slow or unresponsive. Tenants appreciate the clean communal areas, good amenities, and neighborly environment, but report issues with maintenance delays, pest problems, and rent increases that seem excessive for some rent-stabilized units. Some residents mention discomfort with management's dismissive attitude toward concerns. Overall, expect a well-staffed building with some maintenance and communication challenges under this ownership.

Reviews

Former tenant·11 months ago

Cookie cutter and corporate

Pros

Tiffany, one of the front desk employees, is incredible. As is Brad. They were by far the best part of the building. Location is alright. Close to trains but feels a little isolated from Boerum Hill/Park Slope.

Cons

The floor in our apartment sloped and our balcony door didn't properly shut unless locked, which made me believe that our unit had shoddy construction. The new management company inherited incredible staff, but they've fired a number of them within the past year. They're slow to respond and rude when bringing up major issues.

Want Slumlords? Welcome to Dermot and 316

Pros

Dermot is firing the staff at a rapid rate. What’s left of the staff- they are wonderful. Recent new hires are unfriendly and unhelpful but there are a few gems left. The people who live in the building are great. Dog friendly.

Cons

Since Dermot took over the building, the entire community and quality of living has taken a massive nosedive. First of all, despite rent stabilization, Dermot has found some clause in leases so they are jacking rents 1K+ per month per unit. No one understands how they are legally getting away with this, but C-grade apartments with finishes that are falling apart are going well over market rate and if you live here 1 year, beware if you want to renew. They aren’t playing by the rent stabilization rules. They have fired tons of staff. The garbage piles up. The gym is filthy and there have been incessant roach and bug problems. Not to mention the management of the direct building are super rude. They make fun of people who come tour the building (one leasing agent called a woman the B word). The direct manager of the building is brutally rude and will stop responding to emails whenever she feels like it. Building management are uneducated, inept and driving this place to the ground. Hiring relatives to work here- nepotism abound. It’s filthy. There’s no value, and tenants have to call 311 to get anything done. Look at every single other building in the area before you look at 316 Bergen while Dermot is managing.

Advice to the owners
