I stayed in Sandra's aparment for one night. Sandra's apartment is located within a half hour walking distance to Belem's jewels - Jeronimos Monastery and an extra 20 minutes walk to Tower of Belem. I'm not too sure about how far the metro system was since I ubered to-fro the airport and that was a good half hour ride each way. There are some excellent restaurants and cafes within walking distance to grab delicious pasteis de nata, coffee or enjoy a hearty Portuguese meal. Sandra's home is well kept and her restroom is very hi-fi and cool, the showers were really outstanding. The room i booked had a lot of kids stuff laying around but it didn't bother me as much as I only slept in the room at nighttime.
