Rita and João's apartment is comfortable and really well located - you can walk into the city centre as well as easily get to train stations for day trips. I also really enjoyed just wandering around and getting a bit lost in the streets of Alfama.
The apartment is surprisingly peaceful given how close it is to bars and restaurants. As a lone traveller, I felt safe in the area, and walking back at night.
Rita was a really helpful host - there at check in, and on hand for tips and to answer questions. Definitely recommend the place as a great base for exploring Lisbon.
