My family and I spent 3 nights there. We were 4 people.
I would have appreciated two more bathtowels (we only got 6 pcs., 8 pcs. would have been better) and some more glasses (there were only two glasses). Apart from these minor improvements, I thing that the price was quite honest, considering the flat was not too small and that beds were true beds (not sofas to be transformed into beds). Strong point is its location, short walk from/to the nearest subway station on U6 subway line (JosefstaedterStrasse).
