This was an Airbnb nightmare! We arrived within the 5:30pm check-in time that we said we would but found the place dirty with used towels, used bedding, missing bedding, and dirty floors. We notified the host and they sent the cleaner back to address the issues. The cleaner returned quickly but did not knock on the door before entering while we were still inside. We felt suddenly intruded on. The cleaner insisted that they had already cleaned the place. They said that the previous guest had reentered and used the apartment after they cleaned it. The cleaner told us we could leave our luggage and assured us they would take care of things. We left our luggage inside and headed out so they could finish the cleaning. When we returned, we found that the front door was left unlocked. The caretakers do not seem to keep the place secure and the front door did not have a deadbolt to prevent anyone with the code from coming in. The toilet was also making a constant intermittent high pitched noise since we returned that was disturbing our rest. We didn't feel safe or comfortable so had to cancel our stay completely. We also didn't feel comfortable redeeming the included Arboretum tickets because we had to text a private number and received instructions from a nameless person to meet them at an appointed time to get the tickets.
