Studio is pretty nice, modern style. Has everything you need to spend couple days in Vien. Large bed, shower, washing machine, dishwasher. No microwave. Basically, we enjoy everything and have really good time here.
Weak point of this studio is location. I mean, it's really close to Shonbrunn Palace, but it's the only place close. Rest of attractions and monuments are closer to the city centre. Also, you need to ride two different metro lines to be near the studio and you still gonna need ten minutes walk. So I rate location 4 stars.
Also I gave 4 stars for cleanliness, cause our linen (bedding) wasn't quite fresh and stinks a little bit. But still, it wasn't too uncomfortable to complaint about during our stay.
Overall it's still good studio for quite good money.
