What a wonderul family! First of all, I think they are the first hosts I’ve had that have responded to my messages so quickly! From booking to check out, they have been so helpful. The flat is a 10-ish minute walk to U-Bahn Keplerplatz and a little over 15 minute walk to Wien HBF station. The room is very sufficient. It has everything you need and it was very cozy considering it was very cold when I was there! Super comfortable bed and sheets! Thank you for a nice stay!
