We greatly enjoyed our time at the Jazz Corner Hotel. It's an amazing location with easy access to the tram line. We had an incredible view on the 30th floor. The food at breakfast and dinner was very tasty, and catered to a variety of dietary requirements. Unfortunately, we were not able to attend the Jazz Club underneath, as it was fully booked (which is great for them, and not a complaint! Just a recommendation to book in advance for the Jazz shows, which we were not aware of).
Unfortunately, there was an uncomfortably loud noise coming from the bathroom fan - we mentioned this to the front desk twice, but no solution was given, which was disappointing for our 5 night stay.
Other than that, we greatly enjoyed our time at the Jazz Corner.
