I had a fantastic stay in Quartos' place. I found the room and shared areas to be exactly what I needed for my stay in Lisbon, everything was clean and as shown within the pictures, with all of the expected amenities described and even more. Quartos was very responsive to any questions I had both leading up to my stay, and during. The location was perfect for what I needed with buses and the metro very close by.
The room was especially comfortable and really made the holiday, I'd definitely come back if I'm ever in Lisbon again!
