In response to Debra's review, I would like to explain the circumstances of the key, it had been misplaced by a recent guest, but the door from the garage does have a locking key which keeps the apartment secure. The apartment is not in the basement!
Debra asked me if she could use the barbecue (absolutely yes), but what she didn't tell me was that she had planned a party for twelve including teenagers. She made us feel like intruders in our own home.
Regarding the "numerous " times we entered the flat. As soon as Debra and her boyfriend arrived I asked her permission to access the washing machine while she was out, texting her as to the time suitable.i did use the machine twice, both times as advised. On the third occasion of entering the flat, my husband knocked on the door and asked if he could retrieve beer from the downstairs fridge.
Debra used extra linen, extra sparkling water, all without letting us know .
She also refused to check out at midday as requested by me, leaving finally at 1.30. Our council bin was also filled to overflowing.
