Alexandre is a great host, responded quickly altough he wasn't staying in Portugal at the time of arrival. The house is very clean and neat. We got a warm welcome from his dad, and found some lovely sardines and a nice bottle of wine in the refrigerator.
It takes about 20-30 minutes to get into the vibrant city centre area (by public transport). If that's ok for you, this would definitely be a nice place for you to enjoy wonderful Lisbon.
