My stay at Paula's was a bit of a mixed bag.
On the plus side, the listing looks as pictured and is in a really nice area in Lisbon that I've never really seen much of before. Lots of nice bars/cafes and since its near the river, you can explore the area while avoiding a lot of the hills.
The listing was clean and while there is no AC, there is a fan above the bed which was fairly effective, especially with the window closed. The fan does however need to be seen to by a repair man as it is not fully fixed to the ceiling and makes a bit of noise when turned on.
On the negative side, the checkin process was a bit of a disaster. I was informed that key collection was from a nearby supermarket however when I arrived, the information I was given was incorrect. After a lot of back and forth with Paula's support team, I was informed that the keys were to be collected from a place in Bairro Alto which is 15 minutes away and entirely uphill (not great with luggage in 27 degree heat and a low phone battery).
Upon checkin, I noticed there was no washing machine (advertised at the time of booking but since removed) and there was no shampoo or shower gel (still advertised).
I also couldn't seem to get the TV to work (instructions said there was 2 remote controls but only 1 remote was present in the room).
There is a bar outside the building courtyard which does get loud on weekends but the windows do a pretty good job of isolating this when closed. Inside the building however, noise travels very easily. I think many other rooms in the building are also rentals as I could hear a lot of luggage being moved as people would come and go. The door to the listing does not do a good job of keep those noises out so expect to hear people as if they are next to your bed. Depending on the trip you are on, this might not be an issue but the listing might not be recommended for those who are looking for a relaxing pace to their stay.
Overall, I think the listing was good value for money (It was a new listing so the host did have some discounts ) and I think the negative aspects could be fixed easily enough (easier self-checkin, making sure advertised amenities are offered, repair fan and some better sound isolation around door).
While I'd rate it 3 stars due to my personal experiences, if these issues were fixed, I would have rated it higher of course.
