I stayed in Lisbon for 5 days and I couldn’t have picked a better and economic place to stay. The apartment was great and located in a very walkable area. I traveled alone and for being a young woman, I didn’t have any issues at all. Johanna was amazing and they even give you a folder with a lot of information, which comes very handy when you have never been in the city before. There are great restaurants and coffee shops around there. I didn’t take the Trolley but is a street away from the apartment; I decided to walk everywhere :)
