It was a very new, nice, light, well equipped and comfortable apartment with a huge balcony at a recently built area of Vienna with a food store (SPAR) and nice hamburger restaurant (Burger's Bar) in the near, a good public transportation (underground U2) to the city center. Even though the flat was not too big (approximately 27 m2 room space and 18 m2 balcony), but due to the furniture tricks (hidden kitchen and bed) used it was really spacious, so it might be comfortable for even 4 persons, although I used it on my own. I do really enjoyed my staying over there, so I suggest to book it in advance for your next visit to Vienna!
