I'm currently subleasing and the apartment I am is absolutely disgusting. There is mold in the shower and on the walls and the apartment is moist all the time. I try to look at the better side of things but there is none here. The building adjacent is owned by Roland and is very new, nice and well kept which why it blows my mind that this one is in such bad shape. How can a company continue to build when they do not take care of the properties they already have?
I went to the office and tried to get a room condition report and was denied one though the manager was very familiar with the property and said "this is not the first complaint we have had about this property" yet they refuse to fix the issues. I will not be renting any other apts from Roland. I can't wait to get out of here.
