My girlfriend and I stayed in the Ramada for two nights during the Christmas market festival. The hotel is very centrally located being only few minutes walk from the HauptBahnhof and a 10 or 15 minute stroll from the Altstadt where all the markets and sights were.
Reception were very friendly and had good English as neither of us have very good German. The room we were given was relatively small but very cosy and comfortable. The shower/toilet was surprisingly large and both rooms were very clean and bright. There were coffee/tea making facilities as well as a mini-bar in the room.
The breakfast buffet which was included was very well presented and had a very wide choice. There was a slight queue for the coffee and tea on both mornings which was the only drawback.
Overall both of us enjoyed our stay immensely and will definitely be recommending the Ramada for any of our friends that will be traveling to Frankfurt in the future
