I won't hesitate to give the best comments and five stars for Lenka and his room. Lenka has been very helpful and responses to our questions very fast. The room is spacious, tidy and clean, equipped with everything you need. We are three adults with a five year old kid. Lenka fixed the two beds together to make a 1.8m big bed so four of us can stay together comfortably. The flat is in a beautiful historical building, and it's just six minutes walk from the train station. We went to Vienna by train after check out, so it was super convenient. The restaurants Lenka recommended were amazing. It is definitely the best value and the most satisfactory accommodation in our whole trip.
