Sissi Suite II is located in very convenient and quiet area within walking distance from several Vienna sights (Schonbrunn, ZOO, Technical museum). U4 Underground is also very close. The apartment is very comfortable, pleasantly equipped and has all modern features. Great for families with children (in our case business trip combined with family visiting Vienna sights) - it has 2 big and very comfortable beds, central room with plenty of space. It is sparkling clean, and has this stylish touch with Schonbrunn photos. And the best feature - operated with electronic lock, so keyless, no searching pockets :) Martin is a very kind host, communication very quick! I definitely recommend this place to everyone.
