My boyfriend and I stayed at Samantha and Nuno's for 4 nights. They weren't there to greet us, but their friend met us and showed us the apartment and she was very friendly and helpful. We also got a bunch of great tips in Alfama from Samantha and Nuno! The apartment's location is perfect, it's very near some great views in Alafama and it was easy to find it by metro from the airport. I would highly recommend staying in their apartment!
