We (familiy of 5 with 3 kids between 10-14) had a great stay in Lisbon. The appartment is very spacious, comfortable and clean. Also very centrally located. Luis and his team are great hosts. The only drawback were the drugsdealers in the streets around the appartment. They were not aggressive, only sometimes playing loud gangster rap :-). Anyway we didn't feel too comfortable when going out or coming in with the kids in the evening.
