Nuno's apartment is well decorated with modern furnishings and a well-equipped kitchen. It is convenient for all the city centre attractions - you can walk or take a bus or metro to places a bit further away. We would recommend taking the Metro from the Airport to Rato (on the Yellow line) to get to the apartment. Lisbon is very, very hilly but the walking route from Rato avoids too many steep uphill climbs with your luggage!
The apartment is on the 2nd floor and the stairs are a little narrow and steep, which made carry large suitcases up and down a little challenging, but our host offered to carry our luggage up for us on arrival.
There are lots of good restaurants very close by, and a supermarket just a few hundred metres away means you can easily eat in or out.
