We booked this hotel on the day of our stay as we were scrambling to extend our stay in West Coast due to Hurricane Sandy.
The hotel was nice for the price and in line with the other Hilton Garden Inn we stayed at in Frankfurt airport. Service was polite and helpful, rooms and lobby were clean, gym was small (1 treadmill, 1 cross trainer and some weights) but at least it was 24 hours. Complimentary coffee was available at the front desk and if you follow them on twitter they will throw in a free bottle of wine. Free on site parking and breakfast was us13 per pax (we didn't eat). Front desk was helpful - we arrived back late for check our from our hot air balloon trip and they let us check out late without charges.
