Location is perfect, Griechen is very responsive and helpful, the apartment is clean. must say the place is not 100% like the photos furniture is a bit outdated and pillows are not comfortable. But overall it’s a good place to stay in central Vienna, close to everything. One thing that was inconvenient for us is having only one key to the apartment, the building main door closes at night so if one of us is still out the other must wait till they come back to open the door!
