The apartament is at perfect location (less than 5min walk from Rossio and Martin Muniz squares) and offers everything you need for your stay: confy bed (I have a high standard for this), great kitchen with amenities and basic staples (oil, salt, sugar, coffee, tea), good bathroom and shower (although a little small).
Roman was kind to offer us great local tips for things to to, transportation and where to eat. Also, he responds very promptly and is always available.
This is place is a no brainer with you want to stay in the heart of Lisbon.
