I definitely recommend her and her house if you want to have a pleasant stay in Lisbon.
Maria is super helpful on all kinds of topics or issues around Lisbon and Portugal. I really had a pleasant stay in this apartment and will pick this place again without a doubt
Maria, the landlady, has been available since my request to book, she bothered to pick me up at the airport and as to her home, she really looked after every detail so that her tenants can enjoy a really pleasurable stay at her place.
The house is really fully equipped.
The room is welcoming and comfortable with its own AC split.
The internet connection is super fast. You are on a high floor with a nice view, although the area is a bit noisy due to the traffic at every hour. That's a minor inconvenience, though: as soon as you shut the window you're not bothered anymore.
