My wife and i stayed here for 1 night in a quick stop over. The hotel was quiet, efficient and clean. The bathroom looked like it had been recently renovated although the room itself was quite small.
The design is less than ideal- to get to the lift you must walk through the buffet breakfast room- so while you are having breakfast people with luggage are moving through the room.
Overall, quite a nice stay for the price.

We used the Hotel Hetzel for a 1 night layover on our way from the Zurich airport to Dinkelsbuhl, Germany. Despite being only a couple of miles from the Stuttgart train station, it is in a very quiet neighborhood that has the feel of a small village. We took a taxi (13.70 Euros) from the train station because on the map it looked like it would require 2 S-Bahn routes to get to the hotel.

The hotel is deceptively large (bigger on the inside than the outside), modern, and nicely decorated, with good service from the staff. The room was very clean and adequate, with a nice bath and balcony. The only odd thing was having to carry luggage through the restaurant to get to the elevator for our wing.

The breakfast buffet was exceptional and reasonably priced with a good variety. Unfortunately, we didn't have dinner reservations for their in-house Greek restaurant, but it seemed popular as it was full the whole evening.

There was a typical gasthaus just a block or so away that had excellent food and served as a good orientation for my wife's first real German meal.

We stayed here for just two nights, as a base for visiting the Porsche Factory is Zuffenhasen and the Mercedes Benz museum. We hadn't planned the airport transfers and having taken a later than anticipated flight, we arrived at 9:00pm. the taxi service available in the airport was friendly and efficient and the transfer was just 15 minutes and cost 30 Euro - not bad for that time of the night.
At first the hotel seemed small, but inside it was large and airy and our double room had a well-stocked mini bar wonderfully big hot shower and a balcony overlooking the town. The staff were very friendly and did all they could to help us, booking return taxis and advising on routes etc. The inclusive breakfast was continental and plentiful. Location was good, in a small town with a bakery and basic ammenities. The S-Bahn terminal was at the end of the street but the taxis were so cheap and reliable we didn't bother.
On the last night of our stay we ate in the hotels own family run Greek restaurant which was inexpensive, service was quick and the food was tasty and in good sized portions, drinks we chap and very nice and then only a short walk back to our room. dspite the onsite, popular restaurant we had undisturbed sleep and would highly recommend this hotel to anyone visiting Stuttgart.
