Overall our experience was fine. The apartment was a bit cramped for two, but other than that it was good. The location is a bit outside of the city, only a 20 minute walk, or a 7 minute uber, which I would recommend at least going into the centre as the Lisbon is very hilly and uber is quite cheap! Our host experience was not what we were used to. Usually we get to meet our hosts at the start or at the end of our trip, but this didn't happen here which was a shame. In addition to the above the communication was good and the hosts did check in with us during our stay to check everything was well, but was all done through text on Airbnb, which lost the personal touch that we prefer.
The bathroom is tiny as we had expected by reading reviews but this is okay for us, and the bed is quite hard. Other than that, the accommodation is fine, if you are just looking for a private room outside of the hustle of the city centre.
