Hi just wondering how I should handle this. I was in bed this morning at about 10.30am, having worked until about 4am. I heard the door knock briefly (a few seconds, I was half asleep and ignored), and then someone let themselves into the flat. It was my landlady. I called out from my bed "hello?" and she replied that she had just come to clean the hallway and wanted to get some water from the sink. She said immediately - "Oh are you sleeping?" and I said, "Yes, sorry". She went straight back out. I assume she only let herself in as she assumed I wouldn't be there and it would do no harm filling her bucket up with some water. I am not really angry, but I am uncomfortable with this. I'm aware it's illegal, and also don't like the idea she might just wander into my flat whenever she feels like it, without notice and agreement. I want to say something, and really want it to never happen again, but also want to maintain the friendly rapport that we have and not spoil the good relationship between me, Landlady and Landlord. How do I broach it? WWYD?
