What % discount should a tenant receive for a nonfunctioning oven

[E. James Song]

Question for the landlords out there:

My family and I just moved into a condo (that we are renting) but we learned on the first day we arrived that a gas leak upstairs had caused significant damage to our kitchen. As a result, the oven/stove had to be removed, our kitchen cabinets pulled and the entire kitchen flooring has to be redone. Our landlord said she didn't give us a heads up because she thought everything would have been fixed by our move-in date. Well, we're almost 8 weeks out now and they're finally starting construction. My landlord really has been trying to speed this along but the condo association has been dragging their feet. When we first moved in, my landlord said she'd give us 50% off our rent for everyday the construction was going on. Now that were two months in, she's going back on her word and offered $1000 of rental credit, which comes out to only ~ 20%. This has not been an easy 8 weeks as you can imagine. We've had to eat most of our meals out as we don't have a functioning kitchen and the constant presence of the construction crew has made it difficult to have any type of privacy, let alone some peace and quiet for my 9 month old baby.

From your assessment, what % would be a fair discount ? I talked to another friend who was in a somewhat similar situation and they got 50% off as well but they were part of a large apartment complex. They also asked us to provide references to show them what the industry standard would be for a situation like this. Any help would be greatly appreciated. Thanks all
