The apartment is perfectly located for exploring Vienna. Close to transport connections. On our first night we walked up to the (best) Christmas market at the Rathaus and then visited a few bars along our walk back.
The apartment itself is located on the 1st floor of the building (this is not explained in the check-in instructions) but once we found the correct floor, check-in was very smooth.
For a 1-bedroom apartment, it's very spacious and had everything we needed for a long weekend in the city. The underfloor heating was a real treat after being out in the cold all day!
The shower is one of the most powerful I've ever experienced, which was great.
The only thing we weren't expecting was the bedding. It was two single duvets on a queen-size bed, but you know what... it worked really well. The bed was nice and firm and extremely comfortable.
There are a couple of supermarkets nearby which was handy and the hotel up the road had a very nice bar.
5-Stars from Us! :)
