We saw many great reviews about the place, but looks like we found ourselves extremely unlucky with the experience we went through. It was our first day in the country, and we had a early check-in at about 6:30 am. Post several messages, texts, and calls we did not get any response from Jussara and were left stranded in front of the apartment. We waited for more than an hour and were left with no option but to look out for other accommodation. We were just thankful to have found a wonderful hostel "Lisbon destination hostel" above Rossio station that saved us at those early hours.
Jussara responded later in the day, and apologized and tried to make it right, by asking us to check-in even with a request to cancel. But, post the check-in on the second day, she just went dark and did not respond until date, and our 2 days cancellation stuck.
Another thing that we noticed was that right at the door steps, there were always 3-4 guys hanging out and I believe were trying to sell illegal substances, and were laughing at us when we were checking in eventually. We just felt so unsafe in that place purely by this experience, though the location is very convenient to travel around the city. This was a learning and terrifying experience - and that explains our first negative review ever in Airbnb.
