Great location, near Alameda metro station that has two lines of metro, one being the red one which goes to the airport. The room's window has a great view to Lisbon, and there's a balcony with the same view if you want to enjoy the sun. The room is spacious and has a sofa in it.
But what called most of my attention was Samuel's intentionality in trying to make my experience the best possible. Sharing tips about places around to eat, work and do grocery (cheap and good ones), about what to do in Lisbon and how to get around, he was always quick to respond and extra helpful.
One thing to bear in mind: you'll have to go to the fourth floor and there's no elevator, so if you have too many baggage that will take a while, although I'm pretty sure he'd help you with them.
