We spent 3 days in Lisbon at Rui's apartments and it was amazing! First of all, Rui is a highly professional host, as well, as very nice person. He helped us a lot with accommodation, with pieces of advice, even with a print of our boarding passes:)) The apartments are close to a subway station (where 2 tube lines cross), 30 min by walk from downtown. It was very clean inside and there were a lot of light. For 2 person it was even too large (more than 100 sq.km), next time we'll come with a couple of friends;) We highly recommend this place, for sure, you'll love it!
