Hotel Münchner Hof offers a great location, putting you within just a 10-minute walk of Frankfurt Opera House and Staedel Museum. Free perks include buffet breakfast and WiFi. There's a bar/lounge, and rooms offer flat-screen TVs and refrigerators.
Pros: proximity to the train station and trolley was the only positive.Cons: This "motel" is located in the red light district. DO NOT BRING YOUR FAMILY HERE. No Children!!!. The entire place smelled like the Korean restaurant downstairs. My entire room smelled like Kim Chi which to me, smells like burning garbage. I had to keep the window open the entire time just so I don't throw up. The room was a low end motel room. The TV was more like a computer monitor and only a few channels. If you need to use the iron for your clothes make sure you have 5 euros on you. Its the deposit. They must have a lot of guests steal the irons out of sheer anger. I couldn't figure it out.
Very good no frills hotelPros: Excellent location near the central train station, the city center and ethnic restaurants. I was in Frankfurt for 2 nights and this hotel was fine. The decor was bit depressing but I paid less than $50 so I did not expect much. Cons: Tired decor.
