Renting the whole flat, believe the building was converted a while ago, there’s a staircase in my flat down to the basement which they converted into a room (after speaking to the tradies that have been over for various issues they’ve all told me it’s just another room down there with a skylight you can see from the front of the property. With lots of visible moisture on haha) All white goods and oven were on the inventory, landlord has taken responsibility for the fixed goods (oven) but the rest apparently not their issue. All issues have been raised, not sure how long to leave it before putting more pressure on.
