We spent a weekend in Jo46, which is a sweet vintage but modern apartment in Joseftstadt, the "Quartier Latin" of Vienna, within 20 minutes of walking distance from the city center. The apartment is on the ground floor, close to the street entrance but it is quiet and provides superb privacy. The windows look on the inner courtyard. The furniture is vintage but the facilities are modern. There is no kitchen but a fridge, a microwave oven, a coffee maker and an electric kettle. The bed is on the gallery and the place is full of heartwarming little details.
Nicoletta is an excellent host, who keeps the place in mint condition, provides all the equipment you need for your stay (towels, hairdryer, shower gel, etc.) and puts breakfast for you in the fridge. Her coffee is beyond words, and she also has a small coffee shop in the house. We didn't have a chance to try it but we had a lovely time here.
