We had a great time at the grey apartment. it was so nice and comfy and we really liked the interior and the facilities we had. The apartment had it all. Such a warm and comfortable room.
Also, the location was really close to main points we had at the map and it was such a quiet neighbourhood. We would 100% rent it again if we come back to Vienna.
We loved the city and its culture, and having such a comfy space to rest after a tiring walk trip around the city was the best feeling ever.
We totally suggest renting this apartment : 10/10
