While living in the building at 340 w 87, I had several maintenance problems including mice in my unit and plumbing issues. But that all paled in comparison to the atrocious behavior of the company when it came time to move out. Siba made every step of the move out process as difficult as possible, inventing a wide range of fees never disclosed in my lease. I am now months into a dispute with them to recover the exorbitant security deposit they required. Through this process, I've connected with other tenants that were forced to pursue legal action against Siba.
There are millions of apartments in NYC - do yourself (and bank account) a favor and find one not managed by Siba.
