It is a great tiny place if you are out and about a lot. It is even smaller than the pictures, but you have everything you need. Would def recommend for winter stays, but during the summer it might feel trapped. There is an S-Bahn right around the corner and U-Bahn at 7 minutes walking so very convenient to get around the city.
After booking I got some mails that made clear the host is a bigger organization. This feels quite unpersonal, and the check-in and out e-mails made it very hotel-like. I am ok with a host not being there, but this feels very anonymous since it was not one person renting out their stay. However they have a lot of options you can book with your stay to make it more convenient, thus if you like a hotel-like experience it is definitely your thing. They are also very responsive when you have any troubles.
Wouldn’t book again since I enjoy authentic Airbnb’s, but apart from this it was clean and allright.
