The Clarion Hotel Post has much going for it: as central a location as you can find; a friendly, informed, and helpful staff; excellent restaurants; a rooftop swimming pool; and much more.
The rooms are sober, to say the least. Standard and Deluxe (!) rooms are minuscule closets and no chests of drawers: there wasn't even enough room for one person's underwear, let two people with unusual things like shirts, trousers, blouses, dresses, etc. Superior rooms are better. (I did not see a room in the modern addition.)

I had stayed in this hotel twice and both the times it was a wonderful experience. The staff had always been very polite and helpful. Beautiful and classy rooms, Clean and hygienic bathrooms and bath products, Perfect location as it is located in central station and the best part about this hotel is the "BREAKFAST". One must never miss a single day of the lavish breakfast. Lastly I would say I had traveled to several countries but this hotel is my favorite out of all the hotels in the world within my budget.

We stayed at this property for one night upon arrival in Sweden, and it was part of our Volvo Overseas Delivery package. I’d messaged the hotel earlier to let them know that we would be arriving early (our flight from the US landed at 10:25) and they said they’d try to get us a room. When we arrived, they had indeed secured us a room which was nice so we could take showers and freshen up after a long flight, before walking around Gothenberg to keep ourselves awake! We were planning to spend some time at the rooftop pool but it was closed for renovations. I really wish hotels would let their guests know in advance when things like this happen so you can manage yours (and your kids) expectations.

The bed was very comfortable, the bathroom large (even a bathtub!), the amenities (shampoo, etc) were luxuries, and the design features were very nice. The lobby was beautiful. The included breakfast was one of the most generous I’ve ever experienced.

We didn’t need to use the train, but it’s worth noting that the Central Station is right across the street if you do need access to it. We walked across the other direction to the neighboring park and spent our afternoon there. It had lots of lovely green space and a nice playground for a son to burn some energy after sitting in a plane for hours.

All in all, a nice evening and if I needed to stay longer in Gothenberg (instead we drove the next day to Stockholm in our new Volvo), I would have been likely to do it at this property.
