Normally go for cheaper hotels but experience has taught us to pay a bit extra when in large cities to avoid 'dodgy' or 'out of town' areas - this hotel did not disappoint.
Location was excellent. Only 1 minute from S-Bahn Stadthausbrucke station (S1 + S3 Lines) and U-Bahn Rodinsmarkt statiuon (U3 Line). The S1 line is direct to/from the airport (35 minutes - Euro1.90 single). The locality feels very safe and overlooks a small 'square' and canal area that has several restaurants/bars (I really enjoyed the 'Rheinische Republik') and yet is not overly noisy. 20 minute walk to HauptBahnhof, 10 minutes to the Rathaus, 15 minutes to the HafenCity and 15 minutes to the Alster.
Facilities as expected in a 5 star hotel - good sized rooms/bathrooms, air conditioning, clean, staff very helpful and friendly. Spacious communal areas. Comfortable mattress and pillows. There is a spa - but didn't use these facilities - too busy exploring Hamburg !
Although the menu looked good, we gave breakfast a miss as it was charged at Euros 28 pppd - full breakfast (continental - 1 drink plus 2 small croissants priced at Euro 12.50 pppd). Plenty of cafes/bakeries nearby that offer this type of breakfast at a quarter of the price. As is the norm in Germany, no kettle/coffee making facilities - but we take our own travel kettle/coffee sachets so not an issue to us. Nice touch was the umbrella in the room for those rainy days - we did actually have to use it one day and it saved us having to go out and buy one.
I doubt the location can be bettered - we found it central and within walking distance to all the main sights in Hamburg, easy to access the S Bahn for the Airport (and the International Garden Exhibition). The area feels safe and is clean. I would recommend this hotel and will certainly stay here again when next in Hamburg.
Tourist Tax : I know it's not a huge amount but it's a shame it isn't included in the room rate as a hidden cost - I know this is a City tax and not of the hotel's doing - but it sticks in my throat that having chosen to spend my hard earned cash in a particular city, supporting their hotels, restaurants, cafes, museums, shops and generally adding to their economy (in these hard pressed times), they then want to tax me for the pleasure ! - which economist thought of that I wonder - encouraging people to spend their money in your city by taxing them ? Crazy, absolutely crazy.
