Hard to contact, do not respond for e-mails regarding leaving the property, actually I've got answer after 6 weeks, 6 days before due date. I made some improvements in flat I used to live: moved mirror to different room, mounted cupboard with mirror instead of it in bathroom. I put bookshelves in living room. They were ok and handy fitting in this flat, according to the contract I should remove them. To save my work fixing it, and leave some useful thing for new tenants I ask them if this can stay. They replay when I lost my hope for it and discard shelves and cupboard. They replay positive, yes you can leave it this is fine we won't charge you for that. I was furious. It least I receive all deposit.
