The lock to Brett's place didn't work during our whole stay. We had to take our most valuables every time we left the apartment. I informed him several times though the airbnb app because there was no other way to reach him.
Do not bother texting or calling the phone he provides because it doesn't work or he doesn't bother to pick it up or reply to sms. I told him repeatedly about the lock problem, but he came with new keys which didn't work because the electronic look was broken to begin with.
Basically he has come up with a whole system to minimalize any contact with guests giving you instructions on where to find the keys and setting an electronic door code at the entrance of the flat which basically didn't work for our whole stay. I tried to call him to explain him the problem but as the phone he provided never worked this was impossible so we had to leave the apartment unlock every time we left it.
Then the day we were leaving he didn't inform us of the check out time and took our luggage to a hotel nearby without telling us in advance and only announcing it when again through the airbnb app I asked him about it. Once of the worst experience I had in airbnb.
