Apartment: we stayed as a family of 4 adults and 1 toddler, we all thought the apartment is very comfortable, the living room and cooking/dining space is large enough, with plenty of comfortable sitting, it's not just the odd furniture all thrown together but they really thought about how to make it comfy and home like! Wifi works great! The bedrooms also spacious and with lots of wardrobe space as well. The apartment was clean with all promised amenities, there's free parking downstairs if you need which was great for us that were travelling by car :)
The area was better than I expected, the main train station is literally on your doorstep, google show a bit further away! Hauptbahnhof is a huge stations with a massive supermarket and all the shops you can need inside, bakeries, cafes etc. Very easy to reach the city centre and main sights! About 3 stations by Ubahn and you're right in the middle of the old town!
They left various helpful materials for guests like guides and maps! Very thoughtful!
Hosts were easy to reach and talk to from the beginning, Arndt was punctual to welcome us when we arrived so we didn't have to wait around.
I would definitely stay here again and would recommend this to my friends and family! Thanks again for having us!
