The accommodation is the same as listed. Although small, it has more than the necessary utilities for a comfortable stay, most of which we have yet to use because of our short time in Lisbon. The apartment was spotless on arrival, without any unpleasant smell (which, in my experience, happens too often on listings here).
The only downside is that it's not very easy to locate (without a GPS app), even though it is in the city center. Also, keep in mind that you need to pull the door outside while unlocking it - I am embarrassed that it took me more than 5 minutes to figure that out!
