It was fine. The pictures don't really match the rooms, at least not our room. We requested by message, and had confirmed, that our room would have a double bed and city view. We got 2 twin beds pushed together and a view of the neighboring buildings bright yellow walls. We were told that we couldn't change rooms and all rooms were the same.
The mini-bar / fridge was warm so not great for keeping food or drinks in. We also had some take-away that we wanted to reheat and asked if we could put it in the microwave for 2 mins but were told that we weren't allowed to.
The room was very cold on the first night, and the radiator wasn't working. We mentioned it at the front desk and it was fixed later the same day, which was great.
The location is good. Not far to walk to find food or drinks, and within walking distance of Marienplatz.
