We stayed in the apartment for a week for vacation, and were happy with our stay! Clean, and smelled great with the automatic fragrance diffusers.
Apartment itself:
Spacious (for 2 people) with a cozy living room. We definitely enjoyed chilling on the couch after 15 km of walking around Lisbon.
The bathroom is a bit dated compared to the rest of the apartment, but clean and functional.
The kitchen has all the essentials for cooking (which we mainly used for making breakfast).
The bedroom, despite facing the street, was comfortable and quiet, with an AC (we did not need it in October).
Location:
Quiet residential area, with recycling facilities a few meters away. Amadora is a bit away from the city centre, but Uber is quite affordable so no issue whatsoever to get into town. The train station is also very close so you can always get to town for even cheaper.
There were several small supermarkets/grocery stores nearby with all the essentials.
Communication:
Tomás gave us a warm and friendly welcome, and was quick to respond to any questions or issues we had. Prior to arriving, communication was always clear and helpful. Fantastic host!
