Gabriele's place is well-appointed, exceptionally clean and has all the amenities you might need. She's also very clear about her expectations, what is yours to use, what is not, etc. I had plenty of space to unpack, put all my clothes in wardrobe, makeup and such on bedroom shelf, toiletries on bathroom shelf, and some food in the fridge.
On the night of my arrival, Gabriele welcomed me with a lovely snack of bread, cheese, fresh tomatoes and a glass of white wine, and there were a couple chocolates treats in my room. Upon my request, she also setup iron & board for my use.
Each evening, a bottle of sparkling water and an apple was waiting for me. The bed was very comfy as well. In the mornings, she offered coffee or tea and some bread with cheese and jam. The checkout time is a bit early - 10am, but I was so grateful that Gabriele kindly let me leave my luggage for a few hours on my last day, as my flight wasn't until that night.
The location is very convenient - a 5 min walk from Josephplatz station and a couple stops from Hauptbanhof. She also has a selection of maps & guidebooks available to use while you're there.
This is a great place to stay if you are traveling singly and happy with orderly calm and quiet. As it is a shared bathroom, some coordination of timings may be required in the morning, and there is a cut-off time of I think 10pm for using the shower (though not the sink, but I tried to be as quiet as possible when I returned late & was getting ready for bed). This wasn't an issue for me, but if you are wanting something more laissez-faire and want the freedom to make any noise at any time, then this place won't be a good fit for you. Also note that you will need to take your luggage up several flights of stairs (she is very clear about this, so I knew what to expect).
In sum, this was a great find for me and I would happily recommend.
