I traveled to Lisbon for business and i stayed at Nuno's place for one night only. The place is really amazing. It's located in a quite and nice part of Lisbon, a walkable distance from the city center. The place is well maintained and very clean, in a new build apartment complex. It has its own parking space in a closed garage, which was really helpful for me because the city can be a nightmare when it comes to parking spaces.
Nuno is a great host. He is very friendly, he gave me excellent tips for the city. But most importantly he was very responsive and available at all times.
I recommend Nuno's place either for business or pleasure stay in Lisbon.
