Michael's place was ideally located in the heart of Vienna with extremely easy access to multiple subway lines and tram lines. We were thrilled to be surrounded by so many restaurants and shops, as well. The apartment/airport route was a simple and pretty quick one, and there were great sights to see (St. Stephen Cathedral) even in the immediate vicinity of the flat.
The apartment itself was perfect for the two of us: We had ample room to unpack and spread out, but the space was still cozy and comfortable. The kitchen had everything we needed (cups/plates/water boiler/fridge/dish washer) for us to have tea and breakfasts at our home base every morning and enjoy restaurant leftovers in the evenings. (We didn't get ambitious with cooking -- we wanted to try the Viennese food all around us!)
Michael and his friend Marietta were very accommodating with the check-in process, and Marietta was ready and waiting for us when we got there. It was a great place to stay!
