Hi Legal Advice

I live in the Boston area and I moved into an apartment last year. One of the features I loved about this apartment was the in-unit washer and dryer. This was very important to me because due to the severity of my ADHD my executive dysfunction is very severe and any steps that make chores more complicated quickly make the chores insurmountable for me.

Recently the landlord has been banging on my door when I use it, telling me it is flooding the downstairs apartment. I told him I could wait a couple weeks to use it while it gets repaired but I need to do my laundry. He told me it will not be repaired and I have to go to the laundromat down the street if I want to do my laundry from now on.

I'm shocked because I shouldn't have to go and pay to do something that was specifically included in my apartment. Plus now I have this bulky unusable thing in the kitchen that is blocking cabinet space. I'm feeling like this can't be legal right? It's a part of the apartment, it should be repaired right?
