We are a family of 4 who stayed at Tiago's place for 7 nights, (kids are 10 & 12). The apartment is easy to get to from the airport using the metro and also to downtown Lisbon. There are some really nice restaurants and supermarkets nearby which was handy. There is also an amazing market at the top of the street which sold fresh produce. The apartment is really clean and modern. Only slight issue is the noise from the stairs which others have referred to however we became accustomed to it! I would absolutely recommend a stay here for a family.
