Positiv: Nothing because the experience was very bad to be located in an old Wyndham hotel instead of in the Moevenpick Negativ: I booked the Moevenpick at Stuttgart Airport, as I often do, and got a room in the old Wyndham hotel.
Apparantly Accor bought the old Wyndham hotel at the airport that used to sell its rooms for 79 - 89 EUR.
Now, they charged me the same as at the Moevenpick 150 EUR biz rate for this inferior experience, all the room, the heating, the breakfast and the amenities like sauna and gym are below average.
This has been a very dissapointing experience and really a rip off in terms of value for money.

Negativ: Sauna war nicht eingeschaltet, somit war der Wellnesstrakt nicht nutzbar.
