I’ll start by saying the apartment itself was great and the location was perfect. However, the check-in process was a complete NIGHTMARE. I was sent to 4 separate key shops around the city over a full two hour timespan. Each key-shop was over 1 mile from each other. Sat in one key shop for over 30mins waiting for a response back from the host when the provided code didn’t work. I had to use international calling to contact Polymat customer service. Two hours running around the city on foot to find the key and I was offered 10€ for my troubles. 10€!!! If I had taken a taxi from stop 1, to stop 2, to stop 3, to stop 4 and then back to the apartment location it would have been over 60€. Not inclusive of my international phone bill and two hours of my time. Cannot put into words how poorly this was managed by the Polymat team. Hopefully the check-in process is fixed for future guests, because I’d recommend everything else about the apartment itself.
