Cons, the bad
On arrival the double room nr. I was given the keycard of, was already in use, it had a person sleeping in the room.
Due to an mixup with another guest who apparently was sleeping in the wrong room.
I was given another double room, same layout, but there was an big airco noise on the outside wall, the window was open at the time and was extremely noisy, closing the window double isolated glass kept the noise out. No view was between buildings.
The room phone to reception wasnt working, I heard no sound or dail tone, reception told could hear me, but I couldn't. So left it unused.
The king size bed was big but the mattress, was not to my liking, too soft and didnt provide enough support for my weight.
I had cramps, poor circulation during the night due to that.
The shower area was extremely small for a double room.
Standing in the shower, at elbow reach one would hit the glass shielding, uncomfortable.
The pros, good things
the rooms were clean, and had an climate control thermostat in the room. Could easily make it an ideal temp confortable, at no point did i felt cold staying in November with 5deg celsuis outside temp.
The Frankfurt central station was just around the corner, less 5mins walk. Within 10mins could reach Railway or subway, if you knew prior which platform you're going for easy to travel.
Flix bus stop across the street from hotel.
24/7 reception walk in & out anytime, even in middle of night with no hassle or needs for conversations.
