This property is... acceptable. Hopefully after the note I've left for the host, they will find a new cleaning service to employ, and drop the third-party app nonsense they want you to use to communicate with them. If they don't, bring a vacuum cleaner and your own sheets, and hope the home is already at an acceptable temp when you arrive.
The positives: spacious home, with a well equipped kitchen. Beds were varying comfort levels, but generally better than a hotel at the same price point would be. Bathroom was spotless and water pressure good. There's a cute (but costly) restaurant next door.
The negatives: there were crumbs and fingernails on the carpets, weird dried liquid on the walls and ceilings, hand prints on the windows, and stains on the sheets that indicate to me that the cleaning service the host employs is not doing a good job. I think the sheets were clean, but they need some stain remover, as that just isn't a good look. Someone needs to vacuum and clean the floors, and the walls and ceilings need a wipe-down. There was a gummy of some sort smushed into one of the chairs. Just generally lacking attention to detail. Also, the beds only have flat sheets, no fitted sheets, meaning I was always one roll away from coming into contact with the stained mattress cover.
Additionally, the host expects guests to use a third-party app for check-in, temperature controls, and communication. This wouldn't be a huge deal, except the app is terribly designed. I had to reinstall it several times for it to work at all to begin with and even then the app would crash or simply not respond over half the time. I have a brand new phone, so it was most likely not on my end. The temperature controls were bugged - the apartment was either freezing or sweltering, despite being set to 70 or 72 degrees the whole time, and halfway through my stay I was locked out of the temperature controls completely. We just resorted to opening windows while the apartment was on "72 degrees" (felt closer to 78). Information is hard to find on the app, and there is no internal messaging service. It wants you to connect your email to communicate with the host, but gives no guarantee that your email will be kept private. With no privacy guarantee, I can only assume the information will be sold to third parties.
Overall, despite the negatives listed, the apartment is a nice space. If they were to drop the third-party app and get a new cleaning service, it would have earned 5 stars from me.
