This place is a gem! Not only did I stumble upon a great apartment with everything one could need for even longer stays, but the hosts are also helpfuland welcoming. I had absolutely no issues in the 3 and a half months that I was there.
The place itself is super sentral, very convenient and also very quiet even in the middle of the city due to the windowsfacing backyard. They provided me with a fan that was more than enough for the summer days because it actually is pretty cool in the apartment and the heating system works very well too when it's cold. The are restaurants, supermarkets and convenience stores all around and the shopping street is literally your neighbor.
If you feel like staying home and having a cozy dinner, fear not because the kitchen has all the tools you need to cook. From pots and pans, cutleries and plates, glasses cups etc. They also have a very functional refrigerator even with freezer. And if your guests wants to stay over after dinner, that's okay too because the spacious apartment also holds a couple of sleeping couches and in the morning you can enjoy a great coffee from there Nespresso machine.
The hosts were also very quick to respond to all my requests and questions. I couldn't ask for a better host. I really am going to miss the atmosphere and the convenience of living here when having to move further away from city center.
I can only wholeheartedly recommend staying with Theresia and Thomas.
I'll definitely recommend to everyone I know that would want to visit Vienna.
