Management companies

Could anyone recommend property management companies in Fort Greene, Park Slope, Prospect Heights, and/or Clinton Hill? Please note that I am not interested in realtors/brokers, but only companies that I contact directly, without paying a fee, to rent an apartment in the area. Thanks!

Well, our management company is called Galster Management Co./East Realty but I would NOT recommend them!
They are incredibly rude and cheap and so crappy at communicating that if you want to get in touch with them you will have to go yourself to their sleazy office in lower manhattan because no one will ever answer the phone there even if you call every day for a month--multiple times. If someone does answer, they will insult you and speak to you like you are mentally challenged, which you may be for living in one of their buildings.
