Great place, I love the balcony, it's quiet and was very calming experience overall.
There is a TV and a small desk, so remote working was no problem at all. Bed is comfy, kitchen is great, thankfully I could use their Espresso machine :). Internet is incredible fast, like 300mbit down and 100mbit up on the day and up to 500/500mbit at night. The shower has little pressure and you need to wait a bit for hot water, but I didn't felt this too much of an issue on my three weeks stay.
There is a small supermarket outside in-front of the door, elevator brings you up to the fourth floor.
Overall very homey place.
Unfortunately Edmar doesn't speak too much English, but we had no issues communicating nevertheless.
Taxi ride was ~8 Euros via Bolt to the Airport.
Rebolleira metro/train station is 8-10 minutes walk. Expect to get to Lisbon city center within 20-40minutes and if you don't have a car fastest ~1h10m to the Avencas Beach by Metro => Metro => Train.
Rebolleira is located around Amadora, some people link this area with higher crime rate, but everything around the apartment is well lighted, well developed, new cars, new road (and relatively high apartment prices) so I didn't feel unsafe.
Bolt/Taxi at night was about 15 Euros from City center.
