Great location. The apartment is a bit dated and needs some maintenance but if you like the charm of an older home, then this will be perfect for that. We did run into a leak from the upstairs apartment, we were initially informed that the leak had been fixed, but it happened again. Host was responsive in sending over a bunch of towels to soak up the leak. Barrier between upper and lower floors are very thin so it's very noisy when the upstairs tenant is walking around as it sounds like they are in your apartment. It's a good thing that they finally go to sleep at 12 midnight.
Location is within 10 minutes to the best parts of Lisbon like the Time Out Market for excellent food with tons of other great options just around the corner. Metro is close by and Ubering around to the more popular places cost on average 4-6 Euros. You can walk to the Castle, step hills but worth the walk. The Tram is right out in front of the apartment.
