Cila's place is a nice, small but cozy apartment, and has everything you need. Cila herself is superfriendly and very helpful, before and throughout my stay.
I liked the location a lot, as it is in Alfama, the old neighbourhood. This makes for a bit of a steep walk, but nothing insurmountable. Lots of nice places nearby although some nearby squares are less inviting at night. Also close to the metro.
