Casinha de Tia Maria, is a great place to choose when coming to Lisbon. I stayed there for 6 nights because of my work, and i was really feeling like home.
Area is great, the studio has a lot of light and is very cozy.
I would highly recomend it for 1-2 people, if you want to stay in one of the best areas in Lisbon but not in the main touristic area.
Manuel and Philipe will welcome and help you with anything you may need.
Thank you guys!:)
