We stayed in Simeon's apartment for four nights over Christmas with our two adult sons and we thoroughly enjoyed our stay. The apartment is very spacious, open, bright and comfortable yet with a historic feel - and with plenty of room for four adults. It was clean, well-laid out and welcoming after long days of sightseeing. Simeon was the perfect host - he advised us before our trip, he had drinks and snacks upon our arrival and called us our first day to make sure everything was okay. His assistant Daniela made sure of that with a smooth, informative check-in. She and her friend Kersten were both charming. The location is quiet and at first glance might seem off the beaten track but in fact it is a very short 10-15 minute walk into the heart of the old city. A grocery store is about two blocks away and there are some good restaurants nearby. We enjoyed "Schank Zum Reichsapfel", a friendly local place with excellent locally-sourced food, not exactly close to the apartment but near Karmeliten market in Leopoldstadt. We loved walking into the Inner Stadt along the Danube canal every morning. The building has an elevator which was a pleasant surprise in an older building, and the second WC in the apartment was much appreciated. We didn't use the TV or DVD but enjoyed the Bluetooth sound system. Also, you can easily move the mattresses from the raised bunk platform to the floor if you don't want to climb the ladder. All in all, I highly recommend staying here while in the gorgeous city of Vienna.
