As my son went to Lisbon in my place, because I had to cancel my trip due to private reasons, and he is to lazy to write a review, I'll do that for him. According to his stories he had a wonderful stay at the BnB, the historic house was impressive, and the hospitality was great (It was like staying with friends, but then with friends you 've known your entire life (his words))
And the breakfast was very complete and abundant (his words)
If possible, I will surely try to book this BnB when I visit Lisbon
As I did not visit the BnB personally, I am not able to judge on other specific matters.
