I had a good stay at here, but I do feel like I should make note of s few things. These aren't necessary negatives, they were mostly just unexpected.
For starts when it says you're staying at a bar they mean it. It's a great bar, but they play like folke music until midnight every day and you can very much hear it in the room. The wifi is also pretty much non existent in the room. The bathroom access is through an office where you can get wifi access, which is nominally communal spaces but can feel like you're intruding.

Now if none of that sounds like a deal breaker than I highly recommend this accommodation. The location is spectacular, right in the old town near the main station and the lake. The beds are comfortable and the staff were lovely.
