Highly recommend this apartment! Our family of 6 stayed here for 5 nights and loved it! Apartment was very comfortable for all. Comfortable beds with nice linens. After busy days exploring the city, the apartment was a welcome reprieve to rest before heading out again. We were not bothered by street noise, as some reviewers mentioned, despite having windows open. The location was perfect as was the communication with Joao. The only caveat is that if someone has issues with steep stairs, this is not the place for you... but, then, Lisbon isn't the city for you!
That said, we look forward to returning to this apartment if we are again traveling with a group.
