Fantastic house in a friendly neighborhood.
My family of 6 spent two weeks in this house and regretted not spending more time here.
The house is well equipped. There are toys for the kids, and the kitchen is complete and useful for cooking meals at home. My children enjoyed playing on the back porch as there's a slide, scooter, and skateboard. The house stays bright throughout the day thanks to large windows, but they can be shuttered and made dark for putting the kids to bed before the sun goes down. It was also hot (32C or so) while we were in Lisbon, but the house stayed naturally cool throughout the day.
The neighborhood is great for getting a feel for Lisbon away from the tourists. Friendly neighbors said "bon dia" and smiled at my children as we walked by. The house is walkable to many good local restaurants and cafes, from traditional portuguese homestyle food to fancy avocado toast cafes. The touristy sections of town are a quick car ride, or a 15-30 minute walk away. It was great for our family to be able to visit the busy tourist attractions when we wanted to, and retreat to a calm neighborhood afterwards. The house is also easily walkable to a garden with a big playground (Jardim de Estrela).
Henrique is a fantastic host with good communication and attention to our needs. He lives a few minutes away in the neighborhood and was always available to resolve minor issues (even when we locked ourselves out once, sorry!).
Potential things to consider when booking: the house is walkable to most things, but it's on a hill (like everything in Lisbon) so you'll get exercise. The tree on the back porch drops leaves and fruit, so you'll have to do occasional cleanup to enjoy the porch.
We would happily stay here again when in Lisbon :)
