I had to spend a couple of days in Frankfurt for an event
last week and stayed at the Moxy in Gateway Gardens area.
Gateway Gardens is one stop on the metro from Frankfurt airport and is located on the extended threshold between 25C and 25R. it’s the main hotel area for the airport with the b’mine, Holiday Inn, Hampden by Hilton, Meininger, Moxy, Park Inn and others are located here. There are plenty of food options and a supermarket so everyone is catered for. There are various points in the area where all the inbounds on the 25’s can be seen.
I stayed at the Moxy which has six floors and was allocated room 527, from this room you can see the climb outs from 25R. 25C as well as R18 but its all electronics and there aren’t any photo opportunities from the room, no inbounds for any runway can be seen. There isn’t a lot else to be said about the location.
