The appartment is nice and clean and has a good location. However, the host is a company really, who did not react to my questions/messages. I was getting the same automatic replies from the host.
To get the pin code which opens the key locker all guests need to register on a website, and give all their personal data: address, date of birth, id/passport number.
I had to call the company the evening before our arrival to get the pin code because they forgot to send it. Terribly bad communication!
