Liked: Nice sleek business hotel next to a side entrance of the Frankfurt HBF, very easy to locate. Sound proofing was excellent and didn't hear any noise outside even though it's a high traffic area. Breakfast was fine. The room was clean, modern and comfortable.
Disliked: I couldn't find a place to charge my phone in the lobby while I was waiting. They had power sockets all over the place but the holes were covered so you couldn't plug the charger in. Very strange.
