Great tastefully decorated apartment. It's a 5 min walk from a main street the has plenty of restaurants (try Pastelaria Orion for a local breakfast, Yallah for a quick middle eastern dinner). The hosts are fantastic at communication and in making sure all is fine. The apartment is also 5 mins walk to a tram 28 stop. And within a 5-6 euro uber trip to most touristy areas eg alfama, rossio square etc.
The only notes of caution i would share is re the extent of construction around the apartment - it was more than expected but since we were out during the day, it didn't really bother us much.
And secondly, its located on a street with plenty of graffiti on the walls and that is nearby pubs - it can get noisy at night and we did see many empty beer bottles left outside the front of the building in the mornings. While the city did feel safe, this may be something to consider for those traveling with young families. Best.
