Overall, I am happy with this place.
The apartment is walking distance from Magaretenguertel (U4) which is only a few stations away from major attractions. Regina has been very responsive. Check-in was easy and straight forward. The apartment looks same as what was shown in photos and was clean. Heating works well and it was good due to the weather condition.
I had to ask for a microwave as I couldn't find one. Maybe it's one time thing but now I check with other hosts as well. Dining area was small for us, a family of six, but should be ok for two. It'd be wonderful to have more utensils considering many beds in the unit.
It's good and affordable option for large party. I will reconsider this place if I come back.
