If you want your own place, I highly recommend it. It's situated in a nice / quiet area of Lisboa.
You can arrive whenever you want as there is a code to access the appartment / studio. In the next street there is a small store in case you need some late night snacks / drinks.
Easy of acces by metro (yellow line) or bus (727). Just a couple of stops away from the city center.
Antonio is always available in case needed and has some great tips to visit / eat in the area. 👍🏼
