Filipa's apartment is exactly as described in a wonderful area of Lisbon. You're right in the middle of the action - between Alfama, the castle and walking distance to pretty much everything (bring your A game to Lisbon... everything is at the top or the bottom of a hill!).
The apartment was perfect for a couple sharing but be aware that you are in a lively part of the city... if you're looking for a quiet, unenergetic, calm place to stay - look elsewhere outside this area!
Filipa's communication was first rate as was the checking in and checking out process. Overall, a great stay and I would happily return if we were back in Lisbon.
