Paola's apartment is very beautiful, the rooms are lovely and big and the whole place feels spacious. The location is also superb, it is located only a 1 minute walk from the Spanish Horses and Hofburg Palace and it is a very short walk to all of the other attractions in the city.
Unfortunately, at night time it was very loud as there is a bar downstairs and the apartment is not very soundproof. You could not hear the music from the bar, but when the people left you could hear them being very loud. I do not know if this is only for us (we only stayed on Friday and Saturday night, so maybe it is different during the week), but this made it difficult to get to sleep.
Apart from this it was a lovely stay.
