We had a great stay with Gonçalo :) communication was super easy, he has a lady in the house that can help at any time and does the check in with you super conveniently. Apartment was tidy, big, with a lot of light and you can even see the water from the one bedroom. I was also not loud which you would expect living right in the heart of the Bairro Alto. So all in all very recommendable if you want to stay in the heart of Lisbon :)
