We appreciated that the host greeted us upon arrival, even though we arrived passed midnight. I was traveling with my fiancée and my family, we were 8 total. We went straight to bed that night.
In the morning, we were quite shocked when we discovered the actual state of the apartment: food crumbs in the living room, my fiancée and I woke up with glitter on ourselves and our sheets had what we assume were make-up stains. One of the 2 bathrooms was not operational and dirty, and the second one was unsanitary with the shower drain plugged. We had to mop the floor between each person showering. There was mold everywhere because the window wouldn't open.
We couldn't believe it. We were not happy to say the least.
We complained to the host and he said someone would come to clean up properly and with a plumber to fix the bathrooms but nobody showed up. Thankfully we only stayed 2 nights.
To finish on a positive note, the apartment is walking distance to the center of Lisbon (praça do comércio) and the main entertainment area with restaurants, bars and clubs.
However we would not stay there again.
