Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenant reviews of properties managed by Jon Diacomanolis reveal a mix of experiences. Several buildings, notably 338 Prospect Place and 570 Westminster Road, are praised for their spacious layouts, cleanliness, and strong heating systems. Residents value the sense of community, friendly neighbors, and responsive supers. However, communication with the owner is frequently cited as poor, with many noting unresponsiveness and delayed issue resolution, especially concerning pest control and maintenance. Some properties suffer from noise, pest problems, and infrastructure issues like malfunctioning elevators or irregular hot water. Overall, management quality varies widely by building, and tenants encourage better communication and proactive maintenance.

XL Apartments, Good Building

Pros

XL king sized pre-war apartments, not chopped up into tiny boxes, private yard for building, 24 hour door person, dog friendly, friendly neighbor-community for those who participate, beautiful Ditmas Park, free bike storage in basement, laundry room inside building, building well built with windows in every room, heat is good, new boiler went in 2021-2022

Cons

Our apartment is ok no bugs or rodents, but others have issues with roaches. Sound carries between floors, we have very heavy walkers and running children above us. Sound also echos in the terrazzo floored common hallways, but this can be lessened by not yelling and stopping your dog from barking :) Our bathroom could use an update but it’s spacious. Because the building is so well made, a lot of the doors slam closed loudly from air pressure, but you just have to be courteous and not let your door slam. Our landlord is the main owner in the building and it’s very hard to get in touch with them, but thankfully we tend to fix things ourselves like upgrading our kitchen faucet ourselves to a better one that we liked.

Advice to the owners

Communicate with your tenants, so everything doesn’t fall on the Super.
