Thanks for the nice stay, we really enjoyed the modern furnished and clean apartment in a calm street with a metro station right in front of the house.
However, I would have wished to know how the checkin works prior booking since one has to pick the keys from a choice of three pick up points or pay additional 10€ to receive the keys on-site, as I was informed afterwards.
Additionally, the Wi-Fi in this apartment was unserviceable, probably an issue with the router since the wired connection e.g. to the TV was fine.
Overall really nice stay with only some minor things to improve.
Thanks!
