The three days we stayed with Dinah were fantastic.
The building's location is great, close to markets, bars, restaurants (suggested restaurant nearby - Apache, good and cheap food), as well as the bus stop that goes to Torre de Belém (it's on the same street).
The room and the whole apartment are very comfortable, Dinah became a great friend, giving us tips and advice on places and things to visit in Lisbon.
In a possible return, we will definitely stay again.
