Attending this hotel on a business trip, knew I’d be getting in early so I called ahead and asked for early check in and was informed this should be ok. Waited 30 mins while they checked for a room and had to chase up for an update. Given how I’d travelled that morning I had not eaten so I checked on their website and they offer room service. Perfect, I’ll need that! Arrived in my room looking for a menu but couldn’t find one, picked up the phone to call room service using the designated button, phone would not dial, nor would it dial out to SOS on another button which was worrying. Called on my mobile to report the damaged phone and ask how to order and was told they do not offer room service and no food available until dinner. I did say it was clearly on their website and on the phone as a button! But nope, no food options until later. Decided to see if there was anything to drink in my room and found an open bottle of water, who opened this and why is there some missing?! Was going to call down to ask but….phone is still broken. Also pillows were dirty with some black mark on the sides. Honestly, I travel a lot and have stayed in many hotels including others in Stuttgart. This is by far the worse experience I’ve had so far. I maybe a touch h-angry when I write this but it’s a nice modern hotel and very new but service I expected was just not there and in complete contradiction to what was on their website. They’ve spent a lot of time making it look good with a nice theme (Porsche) but the service and basics are missing.
