Figured out that this would be the Melia, one of the other possibilities for this area at 4.5 stars according to Hotwire's "The last person got..." seems to be NH Berlin Friedrichstrasse. However, Melia has a Tripadvisor rating of 4.5, the rating for the NH is 4 at the moment. Very happy with the result as Tripadvisor reviews are excellent and I've never stayed at this hotel before. Amenities shown were: Pet friendly, Fitness Center, Restaurant(s), Business Center, Internet access, Spa Services, Accessible path of travel, In-room accessibility, Wheelchair accessible, Accessible bathroom, Handicapped parking, Roll-in shower. Used the HOTWIRE link as usual.
