I was told my guest would be at my apt at 1 or 2. She asked if I would be around. I said no, and stated the approx time I would be home. I cam home a little earlier to see her leaving my keys where she picked them up from. I introduced myself, and said there was no need to put the keys back if she was going to dinner, and then a man appeared, threw his pizza box in my neighbour's trash (when it was blithely obvious it was not mine) and she said she was leaving. I said that was fine, but to take the keys. She said "No, I'm going to stay at my mother's" and I then noticed neither had a single bag with them. I was too shocked to say more, but quickly let myself in to make sure my cats were safe and while they were, the bed was a pig sty. The sheets were a mess, the fitted sheet had somehow come away from the mattress, the bed was about a foot away from the wall, and my vintage throw I leave at the end of the bed had fallen down between the bed and wall. I can't beleive they didn't notice this, and if they did, they left it. The cooling fan had been left on, as had the bathroom light. A ceramic plate I leave at the bedside table was on the floor and a curtain I drop when guests need privacy as I have French doors, was left down The towels had been used and thrown in a heap in the corner. While I am new to this, I had had the perfcet guest before so this was all pretty gross to me. I realsie she had used my place for sex with her whoever he was. I shrugged it off as I realised with joy I didn't have to deal with her that eveing, but the plus 1 had not been mentioned either, whcih I expect. Has anyone had this happen? I complained and nothing was done, just many sympathetic noises from Air bnb.
