This place is brilliant! I can't recommend it enough. It is close to everything. It literally takes 10 minutes or less walking to Karlzplatz station, which is basically the middle of town ... so no need to catch the ubahn unless you want to go directly elsewhere (I caught it to the Museum area once because I wanted to get there a little more quickly). The Ubahn is very simple and 2 minutes walk from this place.
The house is great, I loved everything about it. It felt like a home away from home. I loved the big stone staircase leading up to it. The room is bright and HUGE and airy. The windows let the light in early in the morning, but I loved this because I wanted to get up and go out and about. The bed is very comfortable. It took me a while to get used to the keys, but they are actually very simple once you figure it out. The check in and out was easy and straightforward. Thanks Kiki!
