Absolutely excellent location for exploring Lisbon - Ricardo's place is a very short walking distance to two metro stations, as well as a train station that runs to Sintra if you're interested in a day-trip. Also very easy to reach via public transit from the airport. The kitchen was well-stocked with essentials and the space was roomy. The street was also very quiet at night, which I understand to be difficult to find in Lisbon. We enjoyed keeping the terrace doors open in the evening and listening to some fado music drift in from the nearby bars/restaurants (and it always wrapped up fairly early, well before bedtime) - it definitely added to the experience. All in all, a great base for exploring Lisbon and the surrounding areas.
