I can't stress how great this studio is! We've stayed here for 2 nights and our stay has been absolutely amazing.
The studio is beautifully designed and wel equiped with all neccessities to make your stay as comfortable as possible. The location of the accomodation is great. It's just a 5-10 minute walk to the nearest metro station, where you can take public transportation or city bikes. It's also a big plus that the studio is located next to a supermarket, so you can always buy some quick errands.
All in all I would recommend this studio to everyone that's looking for a comfy stay in Vienna.
