I had an absolutely lovely stay Goncalo & Miku's airbnb. The location in Estrela was amazing- very low key, and it felt like a local Lisbon experience without a lot of tourist noise. One note is that the building seems to be filled with other airbnbs so there can be a lot of foot traffic and stairwell noise. Apart from that, the unit is beautiful and clean, the outdoor area is a great hangout spot, there is plenty to walk to nearby and I would definitely stay here again if I came back to Lisbon.
