This place is really interesting and was fun to stay at. There are a few tips I would like to mention that could make this stay challenging for some.
-Three flights of long twisty stairs. There is a tiny elevator. However you can not take it when you leave because you need the keys in order to operate.
-There is no AC. Yes this is typical for Europe and Austria, but if you are American traveling in the summer this can come as a sad surprise. There is a small fan by the bed.
-The natural light is great during the day. If you are a light sleeper with sensitivity to light at night/early morning, you will most likely not sleep well here.
-There is a play ground and what looks like a pre-school across the street. If you have the windows open at night and hope to sleep in, you will be up early from children screaming.
-I think this place would be much better in the winter or just a cooler time of year.
Overall, the place is clean, comfortable and in a cool area. I would stay again in cooler weather.
