This is fantastic, spacious flat in a privileged location in Lisboa (Parque das Nações). It's a safe and clean area, close to one of the main transportation hubs in the city (Estação Oriente), giving you access to basically anywhere. All manner of supermarkets, restaurants, shops, bars and entertainment opportunities (don't miss the Oceanário) are readily available within walking distance.
The apartment itself has everything you could possibly need, and the kitchen in particular has some things which you might not even know existed. )
Diogo and Filipa were very responsive hosts, and check-in was a breeze.
Very highly recommended.
