All in All, a great place to stay in Lisbon.
The place is right next to the S. Jorge Castle, in a really nice, old neighborhood.
The flat itself was a bit smaller then expected, but sufficient for us two.
The flat has everything you need and everything looks pretty new.
Location - good; its pretty easy getting down to Rossio Squer for example, however it can be exhausting getting up to the apartment since it is on a hill.
