Despite the good photos, this is the apartment with the worst impression I had so far since I used Airbnb. It is located on 3rd floor of an old building (very good position, 2 minutes on foot from Charles Bridge) with no elevator, so going up the stairs you can't ignore the additive beam that helps stairs stability between 2nd and 3rd floor: not a good start. Anyway, once entered into the apartment, this looks smaller than photos, and that's the first of many bad surprises: furniture (armchair, sofa, pillows, walls...) has stains and look dirty, even the carpet looks not to be washed in ages; there are also broken/rusty/ruined parts (main door handle, kitchen faucet, toilet-paper holder, table surface...). Not to mention dust in the corners and spiderwebs around windows full of small death insects. Also, the floor plan in the announcement isn't updated: the bedroom is now smaller and because of the bed in an advanced position, the door can't be fully opened. The worst room is bathroom, where there's no window AND no system for changing air. Bathtub is very good, but not if you use it as a shower: protective glass has a gap between lower border and bathtub edge, resulting in water all over the floor (with no drainage grid) after the shower.
I also had some concerns about towels/sheets provided, but the host quickly solved them.
In short, I don't recommend this apartment at all, especially at the high price offered.
