Location is very good, walkable and right next to a tram station. Check in was very easy and the apartment is good value for money although the apartment is a bit worn off.
Something very important to take into account is that you can hear everything from the street, which is quite loud, and the music from the bar downstairs sounds like it's inside the room, so if you don't have a super easy sleep I would recommend you to go for it.
Overall our time in Lisbon was great, and we did had all we needed in the apartment.
