We stayed with a small group on an organized bus tour for a long weekend. Ideally located the hotel is close to everything. Although the exterior looks rather shabby, it is quite modern and agreeable from the inside.
Breakfast was very good, a huge buffet with everything one could think of.
Now to the points I found rather unimpressive: When opening my towel after a shower, I found that it was full black shoe polish. Not the hotel's fault that some people cannot behave, but certainly their fault for not noticing.
Next day, new towels had been brought, but again my towel with stained with lipstick and brownish spots. VERY disgusting and most certainly not 5*.
At checkout, I only had to pay a small sum as it was an organized tour, the receptionist charged me took my money and waved me off without handing me a receipt. As the bus was waiting I had no time to argue, but I found that unacceptable.
Some of our group had been disturbed in their rooms for a collection of a so called ' bed tax'. This was very odd and I have never experienced anything like that anywhere in the world. So, would I come back or recommend? Sadly - no. Next time I visit Berlin I will try another hotel
