Our Customer stayed here in June 2010
Our second time in this hotel, and this time we were on the courtyard side rather than the river side.
VERY quiet, almost made it difficult to get to sleep (Good German beer solved that issue though ;-), not that the river side is noisy, just normal nighttime city traffic sounds)
Nice clean hotel, close to the financial district, shopping and the old town centre.
Excellent local transport links, Hauptbahnhoff (Main Train Station) was about 5 minutes walk away, with bus, U-Bahn (underground), S-Bahn (regional) and Schnellbahn (tram) links.
An absolute doddle to get around.
Room was small but fully equipped for our needs and the staff are very freindly and helpful. Breakfast buffet was excellent, and was able to cope with our needs for a coeliac diet. I would recommend this hotel to anyone visiting Frankfurt for a long weekend, excellent for sightseeing or shopping.
