Guido was very eassy to communicate with. He answered all of my questions rapidly during our conversations. He also allowed us to leave our luggagr in the apartment even after we checked out. The apartment is a bit small for 4 people but it is functional and is of good value. The location is great. There were multiple restaurants and bakeries in the neighborhood. The metro was also near. Thank you Guido. We have enjoyed our stay in lovely Vienna.
