The apartment is exactly as it looks in the pictures - it is spacious for two people and is stylishly furnished.
It is in a great location as long as you can manage a couple of fairly steep hills from the downtown area (although all of Lisbon is very hilly)!
Once in the building, it is a steep climb up 3 flights of stairs. There is a functional lift although it is very small (max 2 people or 1 person with luggage).
The apartment felt very quiet and safe but I would have felt more comfortable leaving passports/valuables there had there been a safe.
Got some good tips from the host prior to arrival and they let us check in a little earlier than normal to accommodate our flight times.
Would stay again!
