I requested an early check in and arrived exactly wihin the 30 min window i confirmed with the host, but shortly after i arrived the host entered with a cleaning service because another person in the building used the restroom. I was unsure of who/how many people had the access code and as a female traveling solo - safety was a huge concern. I requested a late check-out too but no one communicated with the cleaning lady and she knocked once, not allowing anyone time to answer and entered the code and got into the apartment no problem. Luckily i had already showered and changed. There is no peep hole to tell who is on the other side of your door and no extra locks - making entry into the space easily accessible to anyone who has the code.
