The apartment has the basics needed when on a city break, except could really do with a washing machine & decent bed. The pull out sofa is ok at best, but generally, if you're not planning on spending much time in the apartment, you'll be fine.
Not the easiest to find in the typical Lisbon streets and the stairs to the flat is a killer.
Alinea was very accommodating to our needs however, so would recommend this apartment if you only fancy the basics from an AirBnB apartment
