In all my travels, I've yet to encounter more helpful and friendly hosts as Teresa and Andy. Teresa spent a half hour at the apartment with me to explain the nuances of the place (how the stove worked, where backup blankets were stored, etc.) and to go over maps and her personal guide to Lisbon, which turned out to an invaluable resource while I stayed at their apartment. On my last day, they not only stored my (extremely heavy) bag at their personal apartment, they invited me in when I picked it up and helped me secure a taxi to the train station.

The apartment itself was clean, fully stocked (from towels and toiletries to cooking basics like garlic and oil), and remarkably quiet for being in the Bairro Alto. I particularly enjoyed the skylights and the windows overlooking the building's inner courtyard.

It was in walking distance to nearly everything I wanted.

Outstanding hosts and outstanding experience.
