Everything was good until the end. I left my sunglasses at apartment when we checked out. Immediately messaged and told this to the host. Also added that, I'm going to pay all posting charges, please send me the sunglasses.
I remember, The day before our check out the host messaged and asked about our check-out time. She also mentioned that, it's for a cleaning lady.
When I messaged the host, she told me that she's going to be only the day after. the day later, host answered that there's no sunglasses at home.
I even remember where I placed it in apartment right before we left, just forgot to take them before checkout. This kind of things happen, we're all human beings, but I didn't expect such behavior from this level of apartment.
