The apartment is very close to the center, we walked everywhere all 4 days we were there. The beds were comfortable and the check-in/check out was easy. Note that the private bathroom opens from the communal living room. I would recommend earplugs for light-sleepers, as the airbnb is shared with other guests and kids woke up earlier than us :D
The rooms is a good value for the price, tram from the airport is literally 3 minutes, train station ca. 11 min walk, closest food store is 5 min walk.
