A very pleasant stay in this apartment perfectly located almost in the center of Vienna and around 25min from several museums to visit. We liked the apartment : luminous, silent, clean and well equipped (towels are provided yet we needed a strainer for our meals that was no where to be found). Sonja and Roman are both really nice and Answer very fast. Watch out : each coffee capsule is worth 1€ and at the end you need to pay a local tax of around 3% of the amount paid for the apartment. In a nutshell, I would totally recommend it because the price, the equipment and the localization were exactly what we were looking for in the first place.
