Hotels in Interlaken with Bathtub

"This hotel is closer to Interlaken West Station than East Station. The bathrooms are shared, not en-suite, and the light sensor is by the door, so the light kept turning off while I was showering, which was annoying. The room itself was spacious and in good condition. However, during my two-night stay, there was a lot of banging and stomping from the room above, so it seems like the soundproofing isn't very good overall. When checking in, they give you two keys: one for your room and one for the bathroom. The owner asks you to always keep the bathroom locked."
