Amazing location in Alfama, by far our favorite part of Lisbon. It's got so much character and good restaurants within walking distance. The neighborhood is lively on the weekends but still very safe and quiet enough in the apartment. Ana and Fatima were very friendly and helpful, communicated with us way before our arrival to answer all our questions and give clear instructions. They also provided helpful tips on demand during our stay (restaurants, things to do). The place was clean, bright, and well furnished.
The only things to be aware of are: 1) the place is a bit smaller than expected (maybe just my own expectations) and the stairs are quite steep (my pregnant wife had to be more careful but otherwise okay for average-build adults). 2) the view of the river isn't really clearly visible from the living room or the bedroom. The bathroom has a partial view and I suspect if you stick you head out the skylight window in the bedroom you can see the river (I didn't try this for myself since it wasn't easily accessible).
Overall, we had a comfortable stay and didn't really feel like we lacked anything. We would visit again!
