Nice budget apartment. I had a good time staying there
Here are a few of the relevant details:
a) bed: comfortable (not too soft)
b) water pressure in the shower: ok (could be a little more but it's really not a problem)
c) WiFi: very good
There are many other short time rental apartments in the house. Mine had windows to Hütteldorfer Straße, which is a quite noisy street with tram and bus and a lot of traffic. I didn't mind too much but it is worth mentioning.
