We had a great time at Pedro & Ruben’s place. They were very helpful giving us tips about Lisbon. The location is great and you can get there from the airport by using the metro and getting off at the Baixa-Chiado station and walking to the apartment might be around 20 minutes. There are very nice restaurants and tourist attractions nearby.
We were able to sleep well as there’s not much noise at night.
I would definitely recommend it to anyone going to Lisbon for the first time.
