This is a lovely, well-appointed apartment. It has everything you need - a good amount of basic kitchen supplies (which for me included olive oil, spices, coffee, washing machine soap, etc). The bed in the loft was cozy and very comfortable, and the neighborhood was very quiet, minutes from a supermarket and good metro stop. The only downside in the noise department is that the neighborhood is right over the landing zone for the airport, and the airplane noises can be loud at certain times of day. It didn't bother me, but it may bother some folks.
I have similar views about the location - it was perfect for me because of what I needed to do in Lisbon. If you want to spend all your time in the historic center, the metro ride might bother you (15-20 min?). But the quiet of the neighborhood does feel nice after the crowds of the center. Just know what you're getting so you're not disappointed! (Also very close to the airport - I took an Uber and it was 7 euro).
