Me and my wife stayed a week in this apartment in the middle of Alfama and enjoyed every moment. At daytime it is filled with natural light and the views over Alfama and to Tejo river are magnificent. You have to climb stairs to the 3rd floor so don't bring anything too heavy as aluggage. But the apartment is really worth the climb! It is spacious and clean, wi-fi works well, there are books and photos around, the interior design is really nice. Our host Pedro gave as many good tips about restaurants, bars, and things to do.
The highlight of the week was a street art tour guided by Mariana, she's so insightful and enthusiastic about the subject and a very good storyteller. We walked about four hours around and up and down (there are stairs!) old Lisboa, Alfama, Graca & Moureria, and heard so many interesting stories about the city and saw dozens great murals and pieces of wall art. You can find different private tours to Lisboa and surroundings behind this link and arrange them with Pedro, https://www.snooperportugal.com/experiences - Mariana is the guide in these. We've met many guides - and Mariana is the top! Don't miss the experience.
Bring good shoes, Alfama is so intriguing to walk around. It is an inviting mace, you never know what a gem you find behind a corner. And Feira da Ladra, Lisbon's famous street market, is just a stone throw away.
