Spent a week at Reinhard's place. It is not large, but has nice design and is well equipped. Location is absolutely fantastic! Museum quarter is just around the corner, subway, great cafes and restaurants, all walking distance around. Check-in was easy, Reinhard met us at the apartment, check-out was even easier - just leaving keys inside and locking the door. That was important as we were departing very early. Apartment is not facing street - that eliminates city sound. There might be some noise from the internal yard or from the staircases in the morning, but at night the place is very quiet. We also liked large Klimt's prints on the wall - reason for many people to visit Vienna.
