It was very big, comfortable, very clean, beautifully designed and very well equipped Apartment. Keep in mind that it is a shared flat, so will share the bathroom with other guests and the kitchen with them as well. The advantage is, you will get (if you want to) in contact with other people and may find new friends :)
The Apartament is very close to the Tram and U-Bahn Station "Reumannplatz" which you can go anywhere in Wien in just a few minutes. If you prefered to walk, you just need about 20-30 min to the Center.
Communication with Michael was clear and easy and he was always very responsive.
All in all, it was exactly what we were looking for and we would stay at Michael‘s place again
