Staying at Elsa's and Rui place was a magical experience.
They are wonderful, communicative and super helpful hosts and they've made the stay that was beginning as a disaster a beautiful journey - we booked it the same day, because our previous host resigned the same day that we arrived to Lisbon!
I would definitely recommend the place for everybody - it's clean, super beautiful (it has a terrace!) and the location is very good - quiet, close to shops, metro and bus stations.
10/10.
