Leila and Ludwig's place was terrific- very clean, spacious and very comfortable ! It is in a wonderful area - very close to the Opera House (5 min walk) and centrally located to great restaurants, and many amazing sites. We were a bit early in arriving and they were very accommodating and flexible. Ludwig helped us get settled and then spent quite a bit of time in walking us through their place , gave us recommendations for places to eat and other suggestions to ensure we had a great experience during our time in Vienna. There was fresh fruit, coffee and other great treats waiting for us. We would definitely stay there again!
