We had a great experience at Filipa & Sergio's place. We had a very early arrival time, 7am, and Sergio was nice enough to meet us at the pace and let us in. He was very nice and gave us a lot of great tips for the city. He even left us some yummy goat cheese and crackers to snack on.
The house itself was amazing. It looks exactly the same as the pictures and is very comfortable and clean. The location couldn't be better being right night to the Se Cathedral and a plethora of good bars and restaurants.
I would highly recommend this place to anyone looking to visit Lisbon. It will make your visit very memorable.
