We stayed in Stayery in Berlin and we were happy.
Pros:
- amazing design of the apartment; - very clean and comfy;
- friendly staff;
- great location;
- easy check-in.
Some minor cons:
- there was no cleaning service during our stay. We had to search and ask staff for a toilet paper when it finished;
- coffee and snacks in the common area are not for free(it's not expensive but considering the price of the room would be nice to get a cup of coffee for free).
- no dish washer
- check out a bit too early
