Guy's apartment was very nice and spacious with high ceilings and great decor, only a 5-10min walk to Schonbrunn Palace (and train station). We met him at our check in time and he gave us some good tips about the area :) the fresh flowers in the room were a nice addition too. He lives in the apartment next door so it was super easy to contact him/get his help when we had some initial troubles connecting to the wifi. He was also kind enough to offer us a later check out and to store our luggage until the end of the day. Would recommend!
