Clara's house is exactly as described. The house is spacious, comfortable, neat and super clean. The location is in the quiet area so we had a good sleep every night. Subway station is within 10 mins by walk and there's a supermarket nearby so you can do cooking at home.
Clara is very responsive host. It was a pleasure to meet her in person.
We enjoyed our stay. Highly recommended.
We will stay here again if we have a chance to visit Vienna.
