We had a great time in Lisboa in Patricia's appartement! :-)
The location ist very central and the view from the balcony is beautiful. Public transport and sights are near by.
Cleanness is okay.
It's perfect, that you have towels and even a hair dryer- but it's helpful to bring a little towel with you to dry your dishes ;-)
All in all it's (especially for the price) a nice place to stay a few days in Lisboa. :-)
