Short story: When I checked in, the space had not been cleaned since the last person left, then when I went out for the day, cleaning staff showed up (without me knowing), touched and moved my clothes, and threw out my shampoo and soap. Communication with host felt very copy-paste without much personalization.
Long story: Over a week out from my stay, I let the host know I might arrive early because of my flight and was told that was ok. Two days out I updated the host that I'd be arriving about 30min before the regularly scheduled check-in, and was again told that was all right. That same day I got the copy-paste message about how to check-in, but the message included another question about when I was checking in. When I notified the host for a third time that I'd be arriving early, I received the literal exact same message thanking me for my update and that the time works out.
None of that would be a problem if it wasn't for the fact that when I arrived at the space there were damp towels in the bathroom, the bed wasn't made, and the trash was full to bursting in the kitchen. I didn't receive any word about expecting anything like this.
I cleaned up most of it myself because I didn't want to deal with such things a moment longer, then left the apartment to hang out with a friend around 3:20, almost a half hour past check-in. Sometime after that, the cleaning people came in and spruced the place up which wouldn't be a problem if they didn't move ALL OF MY CLOTHES to clean up, as well as throwing out my soap. I was very disturbed to see that someone had moved around my clothes. If I had been notified ahead of time, I would not have placed my belongings the way I did.
The host compensated me for the lost soap, but hearing "Okay yes the cleaning lady was running late" after the fact did not feel great. I hope no one else has to show up to an unhygienic space in the future.
