I’ve stayed in Berlin a few times and always at an AirBnB.
Pros:
1) I love the area but it’s not a touristy area so be prepared for that. However, it’s what I prefer and everything you need is within a five-minute walk.
2) You can’t beat the price for the area. It’s very affordable.
3) The apartment was clean and spacious. The pictures are pretty accurate.
5) Consistent and strong wifi.
Cons:
1) I’m not quite sure I understand not offering towels (without a fee) or some basic toiletries. I feel that should be standard in an AirBnB. So come stocked.
2) This is a one bedroom apartment with a king sized bed, one fold up cot, and a sofa bed. Be aware of that.
3) It is noisy. Between the kids playground right out back and the downstairs neighbours who will talk loudly and yell at all hours of the day and night I needed to buy ear plugs.
4) The bed was stiff and tough to sleep in and the pillows basically have no stuffing.
5) There is a balcony that you can’t access. The door has been replaced with a limited-open vertical window.
So if you’re visiting and planning to spend limited time at the apartment then this is a good place. If you want someplace you can kick back and relax then this isn’t for you.
