Over the 4 years all went well. He was receptive in taking care of the mold in the basement, but did not treat root cause. There was a water problem, that was not consistently taken care of. After leaving he was very difficult to get a hold of to get security deposit back. He finally did 4 months later. It wasn't until I filed a case with the city did he return my money. He did say he was renovating the apt in April 2019, so hopefully the first part is taken care of. Beware and get everything in writing!
