Thank you for letting us stay longer, it was very helpful for us, really appreciated.
When we were leaving, the neighbours were curious about the lockbox (how/where/when/ etc), we thought that it's something you should know. also, they are a bit noisy, (especially early in the morning TV, the kids, etc). we say those in private as we understand how it's to be a host and it's good someone to let you know what's going on with your property in a good way and not just spreading hate.
we will definitely choose it again if we visit Athens in the future.
stay safe and see you soon!
