I'm glad I spent points on this property. If you can't put it as a business expense or not spend "real" money on this property, I wouldn't bother.
Impeccably clean room in an otherwise average 4 star property. Nothing really to do in Wiesbaden; I would suggest a hotel closer to Frankfurt proper or even Mainz than out here in this suburb. 30-40 minute train to FRA means a slow (but cheap at 4.10 EUR) overnight hotel for catching a flight.
Slowest internet I have ever seen. You can pay to up the speed though.
They did include a free sparking water, cookies, tea, and coffee in the room which was nice; I couldn't find the ice maker for the life of me though.
