We would highly recommend a stay at Ines & Gonçalo’s apartment!
Immaculately clean and nicely decorated, it has everything you could need for a few days in Lisbon.
We liked the area (nice restaurants and cafes - it felt local rather than full of tourists) and it was a good base for us to walk around Lisbon (occasionally getting on the metro when the hills were too much).
Gonçalo was extremely friendly and helpful when we met him for the keys, and Ines & Gonçalo were quick to respond when we texted asking for tips!
