We really loved our stay at Camila's place. The apartment is situated near the iconic "elevator tram" and the street was always very lively in the evening, however you couldn't hear anything in the apartment, so it didn't disturb sleep at all. The location is great, it is walking distance from the city centre. The famous "Tram 28" line is just 1 min away. If you walk to the centre you pass "Manteigaria" which is supposed to be one of the best "pastel de nata" in the city.
The apartment has a very unique layout and we loved that it was so quirky. It has a lot of amenities including some boardgames and a very helpful book with local tips. The apartment is clean and there was a bottle of local wine waiting for us. We felt that Camila really went out of her way to make us feel welcome and facilitate our stay.
I would definitely recommend this place, if you are visiting Lisbon!
