Come to Pedro's if you want a fair price & a central location. The target market is 18-35 year olds and is not recommended for families.
We were situated two blocks away from the main metro line Marques de Pombal. Pedro's flat is right across from a McDonald's and a grocery store called Minipreço. It's also a 3 minute walk to the Hop On Hop Off buses. If you're in to nightlife or want a killer panoramic view of the city, Bairo Alto is a 15 minute walk away or a 3€ Uber ride.
We had access to WiFi, the kitchen (spices, dishes, flour) and the washer. Pedro was not around much but we were warmly greeted by the wonderful flatmate, who helped us quite a bit.
Overall, we had a great time in Lisboa and I would highly recommend Pedro's.
Other notes:
-I would highly recommend coming with the metro, it is very well connected and takes about 30 minutes to get to his flat from the airport.
-The elevator is small; he lives on the third floor so you may have to make multiple trips if you have lots of luggage.
-The front/room doors are tricky to open. Make sure Pedro shows you exactly how to open/close the locks a few times before you leave the flat.**
