We really liked our "duplex" room for 4 adults at this downtown Frankfurt Trip Inn property on the river and a 15-minute walk to Roemerberg and the Altstadt. The small square-footage was made up for by the lofted 2nd bedroom (with its own TV) and wonderful, tiny balcony that overlooked the river. Although it got warm in the room as it was summertime and we found no way to control the room's temperature, we did have 2 fans in the room (but 1 not working). Be sure to arrive during the hours when the small front desk area is staffed, otherwise you need to make arrangements in advance as far as how to pick up your room key. There was quite a bit of street noise--and we needed the windows open--particularly police and ambulance sirens. Drop off by taxi/Uber or rental car is made challenging due to the bike lane out front and the bikers come racing around the corner! Do not expect breakfast, concierge service, or 24-hour security presence as this is a limited service hotel, but the price, location, and condition of the rooms makes it well worth it.
