Marina's flat in Vienna is an absolutely lovely space, in a building full of charm. It is well-decorated, and perfectly located for sight-seeing in Vienna. We were able to walk to most places we wished to visit, and loved that there are so many unique and delicious restaurants within a short distance from the flat. For further excursions, there is an U-Bahn stop about 10 minutes away, or if you prefer to use Uber, you can reach a lot of destinations for around $10-12.
Marina is a great host, she was easy to reach with questions before and during our stay, and check-in was a breeze. The space is great for two people, but we had two friends join us for two nights, and even with four of us it still did not feel crowded. I especially loved the oversized bathroom that was equipped with laundry. I would highly recommend Marina's place if you are visiting Vienna.
