We only stayed in Lisbon for the one night, but we would definitely recommend this place for a longer stay as well. It's not too far from the tourist stuff, but I definitely prefer staying in this area to staying in the old part of Alfama like we did before.
The place was very modern and comfortable with AC that worked in the bedrooms and we found it quiet at night.
Check-in was super easy and fast. The desk is open until pretty late at night so you don't have to worry about the stress of showing up at a predetermined time since delays can always happen.
