We spent 4 Days at David's B&B. It was a really great time. The Room is in Bairro Alto. Just a few steps to great restaurants and bars. Down the street at Largo de Camões starts a guided walk through the city. You have to do that. Just ask David for the small green flyer with the tram on it. It's for 'free' and you get a good felling for Lisboa. You also have to try the restaurant Le Decadente. For us the best food in Lisboa. Went twice there.
