Staying at Rui's cosy apartment was a superb airbnb experience - he was very helpful, always ready to assist you with almost everything. In his house of books i've felt like at home, and If you're a single woman don't worry - you would feel very comfortable at Rui's place. The apartment is located in the heart of Graca on the very quiet street. I can't way to come back to Lisbon and stay at Rui's place! :)
