The apartment location was excellent, inside the city centre, we could walk to numerous attractions.
We were allowed to leave our luggage after the check out until we catch our flight and we are very grateful about it.
The apartment had many issues though. The second floor didn't have any black out curtains, so we were waking up around 5-6am everyday from the sun.
The bathroom on the second floor has a wall made of glass, so there was no privacy for the three people sleeping upstairs.
There were no toiletries even though they're included in the apartment listing, and there were only 5 toilet papers for 7 people for 5 nights.
There was a bad smell coming from the toilet, but that was a common condition around Lisbon, due to the city's old sewer system.
If the owners pay more attention into the above issues, then the apartment could definitely be better.
