I have to say, that was not a pleasant experience for the three of us to stay at this place.
The check-in and the communication were not good at all.
As our plane to Lisbon was 1,5 hours late, I messaged the host 4 hours in advance to let her know that due to the delay we were arriving at 17:45, not 16:15 as we expected. When we landed in Lisbon, I received a message from her that the keys wait for us at the other place in the city, in a locker 35 minutes walk from the apartment.
If you have been to Lisbon, I might imagine what that means, with all its ups and downs& Exhausted after the plane delay and with the luggage we went there and found the key. But it was not the end of the quiz haha. As we didn't know the number of the apartment (some number was written on the key but it wasn't written on the doors of the apartments in the house; I suggest, the host should have showed us the way if she only had time for us!) as well as many other details. So as we finally arrived, we had to call (nobody answered!) and write messages to find out how to get into the apartment.
The apartment itself was ok. But be ready to climb all the stairs of Lisbon to get there (or take a taxi every time), it's located at the highest point of the city.
Awful experience.
