Unfortunately this turned out to be an unpleasant experience. This was due to three things: poor communication, uncaring service and noise.
- I did not receive any check-in communication, so I had to email them to send me the info, which they did. The check-in instructions indicate that one should somehow place the palm over the keyboard to unlock the flat. I spent half an hour late in the evening trying to get myself in. I was able to speak with the service provider on the phone and they gave me all sorts of weird instructions, such as "Try to cover it with both hands" and "Make sure that you block the light". They flat out refused to apologise for the inconvenience, which was rather unkind. In the end I was able to get in, but it wasn't until the next day that I understood what the main thing was that one needed to do to get in. Basically, the instructions were inaccurate and incomplete.
- I was liaising with their team a lot and they blamed me for not using the instructions. I was sending them videos of how I was opening it and they were incapable of helping me. I have been to tens of Airbnbs of all types of lock-in systems over the last years. Just really poor service and communication from them. I asked for compensation and they refused to give any.

- Also, the flat was facing the entrance door to the building which shut very loudly every time someone used it, which meant very little sleep while I was staying there.
In all the years since I have been using Airbnb, this is the first time I am writing a negative review, but I just thought it is important to help other people who might be considering this option.
