Key was placed in a place that was difficult to reach and non-hygienic (e.g. passing a few garbage bins in a small pathway). Would suggest fixing the broken security box and place it in a location that is easier to reach (especially in the dark) and more hygienic.
Communication could be improved in terms of welcoming guests who were struggling in the dark for keys after a long road trip. We did not feel comfortable to ask any questions as the host seemed to be pre-occupied and showed some frustration in us not understanding the instruction on where to find the key when we arrived.
