Amazing location, right across the street from the ferry/train/metro station. All the basic amenities you need (including a washing machine, no dryer) and your own key for your room. We shared the apartment with another couple for two days but we never had any issues with the shared kitchen/bathroom/living area. It is on the 4th floor but after all the hills in Lisbon you get used to it. Two streets over from Pink Street, great night life. As long as the window in the room was closed there wasn’t really any issue with noise, even on Saturday night. Ana and Hugo had fantastic restaurant recommendations and provided plenty of information on the area. Would definitely recommend.
(I did pay €4.50 the first day to pick up the house key in a public locker, overall not an issue and convenient for multiple guests staying in the apartment, but travelers should be aware to have some change on them.)
