I could not have asked for a better place to stay than Andrei's place in Vienna. The apartment is located in a GREAT location. 3 minutes walk from the Museum Quarter. 6-7 minutes walk to the Winter palace and 12 minutes walk to the Opera and Stephandom.
Also 3 minutes walk to the Volkstheater U-Bahn station which can connect to many others.
The apartment is even nicer than in the photos, spacious and with all the Viennese charm that you would wish for. It is located in the 7th District which is the more hippster part and you can find many small interesting shops in the small alleys next to the apartment.
This has been a fantastic stay. Florian was very kind and was in contact during my stay and offered to clean the apartment half way of my stay, which was very nice and more than I expected.
All in all, I would HIGHLY recommend this place and for sure I would pray I could use this apartment next time I will be in Vienna
