This is a nice spacious flat in a perfect location for exploring Lisbon. We arrived late at 2am and had to go to a different hostel to get the key which worked fine. The reason for marking this down is that there is a very strong smell of drains/sewage in the bathroom. In the beginning this was just in the bathroom however after a few days you could smell it in the whole apartment. If this can be fixed then it would absolutely be 5/5!
