The place is very well located, spot on in the middle of Lisbon. The views from the apartment are great - windows open to a nice rooftop view with the cathedral and churches in the distance. The working desk is great, with a comfortable chair and the internet/wifi connection is really good as well. Opted for the taxi service that they provide from the airport, and they took us to get the keys/do check-in, then dropped us of at the flat - so check-in went smoothly. The place is at a higher floor, but it does have a lift.
On the down side: Was expecting the place to have toiletries, however, only hair conditioner was provided. There was a hand soap there as well. Luckily I had brought my own shampoo/shower gel. The kitchen seemed to be functional, but did not have even a kitchen towel, or a dish rack for drying dishes. The shower was leaky and I couldn't get the top shower head to work. And the pillows & bed were hard for me so didn't sleep that well.
Overall OK.
