Great location! Walkable to many of the attractions you'll want to visit. When things are further away the train station and Metro are just a few minute walk from Flavia's place (there is a great short cut coming and going from Flavia's place through the back entrance of the Rossio train station). There are some hills and steps, but if you're in Lisbon you should not be surprised. The space is ideal for one person, but you could squeeze two in if you had to. The Wifi was a bit weak, but functioned well enough. Overall, I really like the place and would stay again when I return when in Lisbon.
