My friend and I stayed in the apartment for 3 nights, and it was perfect for exploring Lisbon. Alfama itself is a fascinating neighborhood, and within walking distance to the rest of the city. The train/metro station is also close by, and the bus to Belem leaves from just down the street. The apartment is lovely to spend time in as well, with everything you need during a stay. Sara was very welcoming and gave us lots of useful information about the city. I would definitely recommend Artur and Sara's apartment!
