Erich was very kind and hospitable, he waited for us at the exact time we wanted to check in. He explained everything related to the apartment. Place was exactly the same as in the photos and location was perfect, very close to the U-bahn and in the heart of Vienna centre. We are very happy we chose that apartment. The improvement areas are the cleanliness and the noise from the heating installation that was bothering us during the night in the living room.
