We had excellent time in Sandra's beautiful apartment. Even though we did not meet Sandra in person the communication with her went perfectly. We were met at agreed time and given keys to the apartment. The apartment itself was in excellent shape and very spacey so that 5 people could stay without any problems. We also enjoyed the sauna, built inside the bathroom. The location of the apartment is very good and we did not use public transport. All in all a very pleasant few days in festive Vienna.
