Clean and safe within reasonable walking distance, or 2-min (2.30 eu) bus ride, to the airport; conveniently located a few houses down from the bus stop served by two bus lines. (As a solo, female traveler I felt safe arriving back from town after dark and also waiting a well-timed few min at the bus stop to head to the airport, before sunrise).
Flexible checkin/luggage store for my early arrival was a big help and the friendly host/concierge an added bonus. Spotless, bright/airy room with comfortable bed and updated bathroom, with great shower/water pressure.
Minor issue hearing another guest arrive/walk through the hallway, and use their electronic door keypad, in the middle of the night. (Earplugs could easily solve this for light sleepers). Unfortunately, I couldn’t figure out how to adjust the room AC to be sufficiently cool on the warm night I stayed. Had I stayed a second night I would have asked at the desk about the settings on the remote which may have solved the issue.
Overall, a very clean, efficient and pleasant spot and I wouldn’t hesitate to stay again if I needed a place in Lisboa with convenience to both airport and transit into town.
