The place is on the edge of Lisbon and a stop beyond the metro, but still easy to navigate (but may take a little bit more time), but also on the way to Sintra.
The room is large and airy, matching the description and photos, with a small balcony overlooking a quiet street. The bed was very comfortable and warm, which was handy as I stayed in December when it started to get cold and like a lot of places there doesn’t seem to be heating.
Kitchen and bathroom are very clean with own equipment supplied (but no bottle opener).
