We stayed for 5 nights in the Imperial Suite, it was amazing. We were welcomed by Nicola and he showed us arround in the appartment. It was as described on the website. We got cake and coffee and were informed well about the things we wanted to know. The appartment is well equiped and in the heart of Vienna. So almost everything is at walking distance and therefore perfectly located. Our contact between Johannes/Nicola and us was good (quick response). When we visit Vienna again, we come back to this place for sure!
