In the check-in instruction, it is described that a property manager would give me a code to unlock the door of the property, but the reality was there was a smartphone in front of the building entrance and needed to connect with a staff through it.
But, because I expected someone would be available at the door or so, I was not able to realize that and had to ask other guests next to us how to check-in. We had to bother them, but they ewere very kind to give us how to do since they had the same problem.
Then, regarding the response, even though we called the number via my phone or with the smartphone, nobody answered for a while and we were so worried about it if we could get in. After the long flight, I was so disappointed with such an poor instruction and irresponsible operation.
While we stayed there, we helped other guests to show how to check in since they had the same trouble as we did.
I strongly encourage the owner to modify the check-in instruction and processes.
