We loved our stay at Prater’s. The apparent is great, very clean, and the room is really big with a lovely balcony over a great view of Prater’s Park. We received the instructions, well detailed, to self check in several days before arrival so we could prepare it in time. You can get everywhere really easy: downtown Vienna 15min walking or you have the train or metro 2min away. Also the train to the airport, conexiona to the main train station and main touristic attractions (such as Schönbrunn Palace) are round the corner.
I recommend this apartment and host!
