Stay from 21.08 to 23.08.
+ Very good location, nice entrance area, with the aquarium an eye-catcher, great breakfast buffet, 5 stars
+ Massage was great which was booked by me
- / + Wellness area very small and crowded but available, staff very nice
- Standard room on the second floor with a view of the neighboring house and a small balcony with an old bathroom, calcified fittings in bathtubs / Duschkombi and not well cleaned (dirty mirror in the toilet area, hair on the floor and in the shower!, Fan in the toilet area and loud not switchable, this 3.5 stars, rooms themselves otherwise okay and 3-4 star standard
-Reception: at check-in 100 Euro blocked on credit card. Hotel was booked through Business Travel Portal (Employer) and already paid. So far, no removal of the blocked amount on credit card. Despite business travel portal unlike other hotels in Berlin, I stay in Berlin on a regular basis, not when checking in asked whether privately or professionally in the city. Failed to complete form due to tax. When checking out you wanted to charge me this fee and has only searched the form so that the tax is not due. For this a -1. Staff at the front desk but very friendly. All in all I forgive only if it would be possible here a 3,5 because everything together does not make a 4 star standard!
