The apartment is great. Check in was easy and the place was clean. The bed was comfortable and despite being a loft, it felt spacious. There is a washing machine and drying rack which was very helpful as we were on the last part of our travels. There is no air conditioning so it was quite hot during the heat wave in Portugal this week, but thankfully there is a fan which helped a bit. The apartment is up 5 flights of stairs (no elevator) so that is something to keep in mind if you have mobility concerns.
The place itself is great, and the location is close to the metro and shops/restaurants. But there is a restaurant/bar right next to the building and they play music outside each night with big speakers. I would recommend ear plugs.
