The place is cozy, price is reasonable, location is perfect, not too noisy and near restaurants, well-functioning appliances and heaters, good ventilation, comfy bedsheets, relaxing ambience.
If there were like complimentary coffee and tee in the cabinet, that'd be great (specially this winter season). Although the segregation of garbage is new to me, I kinda get the concept of teaching the tourists how to keep the place neat and tidy by taking the trash out themselves. I'm just not sure if there's an option for Airbnb to remind the customer about check-in thru SMS on the day of check-in itself. It could've been better since I don't always check my email when I'm travelling. It was actually my fault that I missed the actual check-in day, but I wish there'd be an SMS notification next time (I also hoped there'd be a little consideration like a refund for the missed hours since we didn't get to stay there for the price we paid for, but nevermind). It was indeed a very short stay, not what I was expecting, but recommended to those who plan to stay in Berlin for a month or two.
