Nuno is a great host, very welcoming with nice recommendations for your stay in Portugal.
The place is close to the airport - about 5-10 mins by taxi or Uber. It is also pretty fast to get to the city centre and we usually took an Uber because they were so cheap. There is a Lidl close by and some cafés but the neighbourhood is rather quiet.
The apartment itself is clean and well-maintained. It is perfect if you are looking for a comfortable stay in Lisbon.
