Elsa didn't exist for us. Pedro for initial communication when booking, then someone else for check-in who never responded to my messages. Always feel that's misleading if the AirBnB isn't hosted by the host, but subcontracted to someone else. Personally think AirBnB should tighten up on that.
Bring your own Toilet Paper!
We got 2.5 rolls, for 4 adults for 3 nights ... when I asked for some more was told the supermarket was very close ... well not if you don't have a car (which they knew), it's a 25 minute walk each way. Just profoundly irritating on a short break to be worrying about toilet paper when it's such a cheap thing to provide. And 2 coffee pods between 4 of us.
No mattress or pillow protectors on the beds, that is a bit unhygienic to me.
Very good value and good location, especially if you are a family. Photos are very flattering, it is a little smaller than it looks, particularly the bedrooms with very little wardrobe space. There was a musty smell, but that was probably down to the spring weather and higher humidity.
Ubers were easy and cheap to get into central Porto.
