We enjoyed a four night stay in Walter’s lovely apartment. Communication was quick and seamless. The apartment is a nice space - big sofa and windows in living room, well-equipped kitchen (nicely stocked with tea and coffee), bathroom with hand-held shower,, and best of all, a super comfortable bed with nice linens and pillows - a rarity! . It’s no more than a 3 -minute walk to Viena’s public transport . Definitely recommended!
