If you stay at Rafael’s I think you’re in for a treat. The apartment is perfect size. Has a great layout aswell as some great amenities. Nights in front of the TV. Coffee in a cafeteria in the morning. Good shower. Seperate toilet. Also, Vienna being so accessible with transport the location isn’t an issue. In fact for anybody who can figure it out, location is perfect being 5 mins away from the U4 Schonbrunn stop.
This flat isn’t for the faint hearted would be my only suggestion. Being young and fit is fine. Perfect in fact. If you struggle a bit with stairs I would note that you must climb 3 floors to get to the flat. And the beds ladder is also an issue for some, not for me. It added to the charm for myself with how well Rafael has used the space he has in his apartment.
