Location / Great location, super central and in the best area of town for restaurants, bars etc. Also opposite Cervicheria, one of my favourite regular spots when I'm in Lisbon.
Furnishing & Comfort / Basic. Its clearly just a 'turn over' apartment. Cheap beds, limited storage, not much in the way of furnishing, cheap sheets and badly equipped bathroom.
Sleep / Not great. The floor of the apartment above is not sound insulated. No problem if you can sleep deeply, but if you think you'll notice the sound of walking and talking upstairs, you won't get a full nights sleep.
