This apartment was great for our family trip to Lisbon! We had 10 people but there was plenty of space for everyone. It was very close to the metro too. Our host was very helpful, she even helped coordinate our ride from/to the airport.
It is good to know, however, that each of the rooms has air-conditioning except one room upstairs. Thankfully it wasn’t too hot during our stay, so the fan she provided was enough.
