Mauro & Sara's place is an excellent option. I loved staying there for 11 nights. Location is great, near the airport, Parque das Nações and Vasco da Gama shopping mall. It was very clean! It's spacious. Access and parking space is very good. The apartment is very well furnished. The building is very well managed.
A special note. Due to COVID-19, I was going to get stuck in Lisbon and Mauro put me at complete ease in terms of staying there as much as I needed and not worry about extra expenses. I wasn't expecting and it was very heartwarming. The couple deserve 6 stars for this offering.
