I'll highly recommend this hotel - For starters, the hotel has one of the most fascinating settings inside the lobby: a 25-metre tall cylinder-shaped aquarium. The room is your typical size room but has several details that made me think, "You go German engineering and efficiency!" For instance, they managed to put in lots of shelves, the trashcan in the bathroom tilts out from underneath, the light switches by the bed control all the lights in the room (I was delighted to not to have to get out of bed to turn off the light right by the entrance!) The room is of simple and clean design. There are no frilly decorations but everything feels elegant. The bed is very comfortable (almost to the quality of Westin's heavenly bed) but is on the harder (but still comfortable) side which was fine by me - I slept very well. The bedsheets are of high thread count and crispy clean. The whole room, the entire hotel is clean.

Perfect location: It is located right next the Berliner Dom and the museum island (Museumsinsel). There are several (though touristy) restaurants nearby. The nearest metro stations are within 10-minute walk.

One complaint #ProTip - when I purchased the ticket to go "inside" the AquaDom from the front desk, the man neglected to tell me that AquaDom is actually part of this indoor entertainment park called Sea Life Centre, it's about 2 blocks away from the hotel - you need to bring the voucher to the main entrance of the Sea Life Centre to exchange it into an actual ticket. You could go through the Sea Life Centre and see all the exhibits there, ending at the Aqua Dom which is in the next building (aka the building where the hotel is at) or you could take the ticket and walk back to the Aqua Dom entrance. There was a wait about 30 minutes to get into the AquaDom - which I did twice due to the front desk's failure to inform me of this "minor detail".
