Nina's apartment was in a safe location with easy access to everywhere we wanted to go. She will give you plenty of suggestions on places to try. The apartment itself was cute, but small. Since we were out and about all day/night we didn't mind the tight quarters. The best part was no keys! She has lock codes on all the doors which made everything easier. She even let us check in hours early since our train arrived in Vienna early morning. Highly recommend staying here!
