We chose Ibis Styles Wien City because its location and because it offered parking. Unfortunately, when we arrived at 6 o'clock, all the parking spaces were taken. The receptionist recommended a public parking garage, which is cheap (3,40 euros per night) - it's about a 10-12-minute walk from the hotel - which is not bad, but it isn't comfortable either, especially when it's raining.
Our room was located on the Wahringer Gürtel side of the hotel - parallel to the local train route - it's very loud, even with closed windows, with trains going regularly.
The breakfast area of the hotel is very small, the signs in the lift draw our attention to this fact saying, "we have to advise to choose the earlier breakfast hours ... as it might happen that you will be asked for patience staying in a waiting line." From 8.30 the room was really crowded.
The room was OK - it was a pleasant surprise that there were 2 seats ( a chair and a pouf) - usually there is only one chair in Ibis hotels, although they have a small bench).
The receptionist (Paul) was friendly and helpful.
