This place is great and sufficient if all you need is a place to crash and will be spending most of the other hours in the day outside. The host had mentioned that there was a vent in the room (my room had no window which was clearly communicated in the beginning before I booked) but I did not notice any and as a result the room easily got stuffy and a bit hot. Otherwise, the place is very central for your first time in Lisbon and is a great value if your plans are to be out enjoying the city :)
