Linda's place is amazing. It's about 5 min walk to Schönbrunn Palace and about 5 min walk to U4 line that gets you to the center of Vienna in about 15 min. Very convenient. We stayed at the end of July when it was very hot outside during the day, but it was never hot inside the apartment despite the absence of air conditioner. There is simply no need for air conditioner as the building has very thick walls. Communication with Linda was also a pleasant experience, as she provided prompt and helpful responses. Highly recommended.
