This was a wonderful hotel for our family of 5. Rooms were large and clean. The breakfast was lovely and we enjoyed being able to grab a cocktail at the end of our day. We would definitely stay here again.

Fabulous room spotlessly clean, great location helpful friendly staff. Great we could leave our bags there after checkout before leaving for the airport. WiFi and door card didn’t work initially making check in a little more of a hassle but really a very minor issue as staff were very helpful and sorted it pretty quick. Would highly recommend

Nice place, easy walking distance to the city center and the zoo. The hotel was quiet to sleep in, but the pillows could use some updating.

Great location and lovely view of the river. Room was very well laid out. Staff was amazing. Highly recommend the Flag Oskar M!
Large units that are great for longer stays where you want some room to stretch out. Location was convenient to a lot of Frankfurt, staff was all very nice, and everything was brand new. Great restaurant with a good breakfast in the ground floor.

Been to FRA dozens & dozens of times, and never stayed here; this will be my next default location for all future trips! You can't beat the location and the views, the staff is fantastic and it really is just a great solution - even with a family.
