This is one of the most central locations in Lisbon. From here, you can walk to most points of interest. You can walk to bars and restaurants. And you can walk to the ocean!
Further, this apartment specifically is adorably decorated with all the items you need to feel comfortable. My friend and I stayed here for 3 nights and started calling it "home" immediately. It is also a great value at this price!!! Whenever I come to Lisbon, I'll stay here!! 5 stars!!!!
