Joana's apartment is a great base for exploring Lisbon! We were warmly welcomed by Claudia who provided us with an invaluable map of restaurants and attractions which we used throughout our stay.
The apartment is located right by the castle which makes it perfect for exploring the Alfama area. Other districts are easily accessible by tram or walking (Lisbon is a very easy city to get around on foot if you don't mind hills - we didn't)
The apartment itself is cosy but clean, with a gorgeous balcony overlooking the river. A well furnished kitchen made days when we wanted to eat at home a breeze. There was an air conditioning unit in the kitchen, but we didn't use this despite temperatures reaching around 30ºC as the apartment was naturally quite cool.
The only minor downside was that the accommodation is a little noisy from being on a touristy street and you can hear people coming and going from other apartments down the stairs. It didn't disturb us but something to be conscious of if you are a light sleeper.
The area was really safe and had excellent dinner spots close by. Thanks Joana and Claudia!
