I had a great experience with the Aparthotel Krone! It is self check-in, which I had no problems at all. I just had to check my expedia messages where everything is communicated. It was easy to message with someone, they always responded. It is located in Unterseen which is by the train station Interlaken West (8 min walk). Still extremely close Interlaken and walkable to Interlaken Ost (maybe 20 min) Unterseen is the cutest town with everything you need! Honestly a fantastic location and I thought the price was very reasonable for how expensive the area is. It had everything we needed. It was clean, has AC, bed was pretty comfortable and had a cute outside balcony to enjoy. Would definitely recommend!
