I had a great stay at Clemens' place. The check-in and check-out were very easy. The apartment has a nice couch perfect for relaxing and it is very well equipped. There is a small kitchen area. The bathroom is tiny but well equipped. Clemes' place is very close to U1, just two stops away from Vienna International Centre and few metro stops away from Stephanplatz. Clemens was very welcoming and gave me useful indications about the area. I absolutely recommend this place.
