Marls was very friendly and responsive, and included great instructions as well as helpful tips.
We picked up the keys at a 24/7 shop in the neighbourhood and found the apartment easy to find.
There seems tho have been a mix-up and we got keys to apartment 11 (instead of 9, which we booked), so the apartment we were in looked quite different but it was perfectly fine. It happens.
The location is great, quiet, yet alive with locals, and the metro station is literally next door. In the back there is even courtyard where we could watch birds and squirrels while we were eating our meals.
The only part where we ran into some issues was the kitchen:
• we could not get the dish washer to work, even after reading its official manual online
• the faucet in the kitchen sink is way too low for either washing up or even filling up the pots
• the knives’ handles are sticky (probably degradated plastic), and a few more cups wouldn’t hurt either
