Empress Sissi's central jewel is a fonderfull apartment. The position is great: pratically in front of the Schloss Belvedere and the usefull tram 71 stop which connect you with both the historical centre of Wien and the train station Wien Rennweg.
The apartment was very clean and there were all the facilities you need. We had interaction with Martin's assistant Ying and the comunication was clear and reactive. Plus we asked to keep the baggages beyond the check out time and there was no problem with that.
In conclusion we had a great stay and hoping to came back soon!!
Thank you!
