This apartment was a delight! Alp is fantastic to work with. They were responsive, helpful, thorough and flexible around check-in and check-out. The apartment itself is in a great location right by the Opera House, walkable to all things in Central Vienna and numerous forms of public transportation. The Apartment is BEAUTIFUL and sunny, with multiple outdoor decks, a cool penthouse layout and very modern amenities. The unit is well furnished and easily sleeps 6 (7 including the sofa upstairs). Really a great find and a great host to work with.
