My partner and I spent a week at Joao and Sandra's apartment. It is a beautiful place with it's own little balcony which gets the sun all day. It's in a safe and quiet area with lots of nearby attractions, also within easy walking distance to other neighborhoods and transport (to places such as Cascais and Sintra). We were welcomed by Joao - and a great selection of Portuguese snacks! - who gave us lots of great recommendations, they left a little booklet with all the information we needed which we referred to a lot throughout the trip. Joao and Sandra made sure we could contact them about anything if we needed to and checked in to make sure everything was okay. They kindly booked us a taxi back to the airport which was really helpful. They were great hosts and the flat is not only beautiful and in a nice part of town but so clean and spacious as well. If you're thinking about booking here I'd highly recommend it!
