The place itself is great, albeit noisy. However, we did not hear from the host once we made the reservation. That's fine; he had check-in instructions.
However, we arrived to the place in Athens, and the photographs of the lock boxes were out of date: In the photo, there were two, but there were several more once we arrived. We tried the code on several different boxes with no success. We had no wi-fi either because that was not provided prior to arrival, and we were outside.
After a hot half hour or so, we were finally able to get service and message Christos. To his credit, he responded quickly. However, the check-in instructions were clearly outdated, and he had to provide new ones. That is unacceptable and inconvenient.
Otherwise, the location is great and convenient, though again, it is quite noisy.
