This was a very convenient location, whether for transit connections from the airport, to and from sights, access to supermarket and shops, it was well-situated to see Lisbon. The climb to the top (4th) floor was well worth the view. The space was comfortable, getting a good breeze from the large windows, most of the basic amenities were there, except do remember to bring your own toiletries as none are provided. The Sé Cathedral is right across the street, and if you don't want to stray far for a meal, the cafe Cruzes Credo on the ground floor of the building serves tasty, fresh, and relatively inexpensive food and drink. The hosts were communicative and prompt with responses. Overall, I would definitely recommend Birds Apartment.
