On the plus side:
the location is perfect! you have everything you need around you and I explored lissabon only by foot. It is more spacious than it looks like on the fotos and the bed is very cozy. I could check in an hour before without a problem an the communication was quick and friendly.
on the down side: cleanliness should definitely be improved, I just didn't feel that comfortable... although small improvements were quickly made on my request. In general I think it is overpriced, as some of the interior is quite rickety (f.ex. showerhead). It would be a convenient place to stay if it were for another budget.
