Sam was always open and quick to respond. There was enough space for two separate travellers. Good public transportation links. Easy to reach Praca do Comercio and Rua Augusta by foot. Please pay attention to the stairs mentioned in the listing. There really are quite a few in the building to reach the apartment and you will be going up the hill from metro station Sta Apolonia. There is a lot of going uphill in Lisbon in general, so just be prepared.
