Céu's place is lovely: very well decorated, superclean and very quiet. I spent 3 nights in her beautiful home with my sister and really appreciated the advice Céu gave us concerning activities in the city. We always enjoyed speaking to her, at the same time she provided enough space for us to spend time in privacy. This is the way airbnb should always work!
Céu was always trying to make our stay as pleasent as possible, also being super flexible with check in and out.
If I should visit Lisbon again, I'd definitely try to stay at her place a second time :)
