I would definitely recommend Gonçalo's listing! It was in a perfect location, close to delicious restaurants and fun nightlife. Gonçalo is definitely a super host! He communicated very well throughout our whole time and gave us many recommendations for restaurants, bars, nightlife, cafes, touristic locations, etc. He provided in-depth descriptions, locations and even contact information for all of these places! He is probably one of the best tour guides and references you can find in Lisbon :)
