I booked this on the internet for a three night stay. The Das Spenerhaus is a spotlessly clean wonderful hotel. The staff are professional and excel at customer service. The location is great close to the metro and the cathedral is a lovely next door view. Comfortable room, found the mini packs of gummi bears a nice extra. Frankfurt is an interesting city and the few days we spent here seemed way too short. Would return as it was a great find.
